This document summarizes the design of a single edge triggered D flip flop using the Gate Diffusion Input (GDI) technique to reduce power consumption. GDI allows implementing logic functions using fewer transistors which can reduce power and delay. The proposed D flip flop uses a master-slave configuration with 4 GDI cells and samples data on the falling clock edge. Simulation results for a 180nm process show the GDI design uses 18 transistors, has average power of 1.77uw and maximum delay of 5.48ps, providing power reductions of 40% over conventional designs. Therefore, the GDI technique is suitable for low power applications requiring high performance.

Basic signal processing system design on fpga using lms based adaptive filtereSAT Journals
Abstract
Adaptive digital filter based on LMS algorithms widely used in the area of digital signal processing to iteratively estimate the
statistics of an unknown signal. Design of an adaptive filter is based on three major computing elements namely multiplier, adder
and delay unit torealize the Finite Impulse Response (FIR) filter. The filter weights( coefficient) of the FIR filter are adjusted
automatically by Least Mean Square of the error so as to match the adapted output to the desired input. This paper explains the
design of adaptive filter by two approaches. One is model based approach and other is Field Programmable Gate Arrays
(FPGAs). The model based design approach is developed around MATLAB, SIMULINK and SYSTEM GENERATOR tools, which
provide a virtual FPGA platform. Modern FPGA include the resources needed to design efficient filtering structures. The LMS
algorithm has been implemented on CYCLONE II EP2C35F672C8 FPGA device, using ALTERA QUARTUS II development
platform. The three major demonstrable applications cited in the present work are System Identification, Noise reduction and
Echo cancellation.

Design of Multiplier Less 32 Tap FIR Filter using VHDLIJMER
This Paper provide the principles of Distributed Arithmetic, and introduce it into the FIR
filters design, and then presents a 32-Tap FIR low-pass filter using Distributed Arithmetic, which save
considerable MAC blocks to decrease the circuit scale and pipeline structure is also used to increase the
system speed. The implementation of FIR filters on FPGA based on traditional method costs considerable
hardware resources, which goes against the decrease of circuit scale and the increase of system speed.
It is very well known that the FIR filter consists of Delay elements, Multipliers and Adders. Because of
usage of Multipliers in early design gives rise to 2 demerits that are:
(i) Increase in Area and
(ii) Increase in the Delay which ultimately results in low performance (Less speed).
So the Distributed Arithmetic for FIR Filter design and Implementation is provided in this work to solve
this problem. Distributed Arithmetic structure is used to increase the recourse usage and pipeline
structure is used to increase the system speed. Distributed Arithmetic can save considerable hardware
resources through using LUT to take the place of MAC units

Design and analysis of optimized CORDIC based GMSK system on FPGA platform IJECEIAES
The gaussian minimum shift keying (GMSK) is one of the best suited digital modulation schemes in the global system for mobile communication (GSM) because of its constant envelop and spectral efficiency characteristics. Most of the conventional GMSK approaches failed to balance the digital modulation with efficient usage of spectrum. In this article, the hardware architecture of the optimized CORDIC-based GMSK system is designed, which includes GMSK Modulation with the channel and GMSK Demodulation. The modulation consists of non-return zero (NRZ) encoder, an integrator followed by Gaussian filtering and frequency modulation (FM). The GMSK demodulation consists of FM demodulator, followed by differentiation and NRZ decoder. The FM Modulation and demodulation use the optimized CORDIC model for an In-phase (I) and quadrature (Q) phase generation. The optimized CORDIC is designed by using quadrant mapping and pipelined structure to improve the hardware and computational complexity in GMSK systems. The GMSK system is designed on the Xilinx platform and implemented on Artix-7 and Spartan-3EFPGA. The hardware constraints like area, power, and timing utilization are summarized. The comparison of the optimized CORDIC model with similar CORDIC approaches is tabulated with improvements.
The Field Programmable Gate Array (FPGA) industry is expanding both in market share and in innovation. The tailored FPGA features make them a better choice to include FPGA in an increasing number of applications in the upcoming years. A constant development of FPGA technology has led to minimize the gap of performance levels between FPGA and Application Specific Integrated Circuit (ASIC). Hence, in recent years, FPGA based platforms are proven more attractive than ASICs since their performance is high in addition to the low cost of the development process and short time to market. Therefore, nowadays, FPGA is highly attractive for a huge range of applications in communications, computing, avionics, security, automotive and consumer electronics. Field Programmable Gate Array industry has shown a steady growth with a market prediction value of USD 9 billion by 2023. Currently, the FPGA companies started growing in reserch areas such as Artifitial Intelligence (AI), Internet of Thing (IoT) and LIght Detection and Ranging (LIDAR).

A Low power and area efficient CLA adder design using Full swing GDI techniqueIJERA Editor
The low power VLSI design has an important role in designing of many electronic systems. While designing
any combinational or sequential circuits, the important parameters like power consumption, implementation
area, voltage leakage and performance of the circuit are to be considered. Design of area, high speed and powerefficient
data path logic systems forms the largest areas of research in VLSI system design. This paper presents
a low power Carry look ahead adder design using Full swing Gate diffusion (FS-GDI) technique. The proposed
CLA implementation utilizes improved full-swing GDI F1 and F2 gates, which are the counterparts of standard
CMOS NAND and NOR gates. The basic Gate Diffusion Input (GDI) logic style suffers from some practical
limitations like swing degradation, fabrication complexity in standard CMOS process and bulk connections.
These limitations can be overcome by Full swing GDI technique. The proposed technique utilizes a single swing
restoration (SR) transistor to improve the output swing of F1 and F2 GDI gates. A 16-bit CLA is designed and
Simulations are performed by Mentor graphics 130nm CMOS technology ELDO simulator. Simulation results
have shown a greater reduction in delay, power dissipation and area.
The rapid growth in the use of portable system has triggered the research effort in low power microelectronic. This is due to the fact that the battery technology is not increasing with the same pace as the microelectronics technology. Only a limited power is available for the mobile system. Therefore low power design has become a major design consideration. Modified Gate Diffusion Input (MGDI) is a low power design which is a modification of Gate Diffusion Input (GDI).GDI is the lowest design technique, which is suitable for designing fast, low power circuit using reduced number of transistor. The main drawback associated with GDI is that the bulk terminal is not properly biased thereby the circuit exhibits threshold drop and it can be fabricated only in Twin well CMOS or Silicon on Insulator (SOI) process. So to overcome this MGDI is introduced.
Efficient Design of Ripple Carry Adder and Carry Skip Adder with Low Quantum ...IJERA Editor
The addition of two binary numbers is the important and most frequently used arithmetic process on
microprocessors, digital signal processors (DSP), and data-processing application-specific integrated circuits
(ASIC). Therefore, binary adders are critical structure blocks in very large-scale integrated (VLSI) circuits.
Their effective application is not trivial because a costly carry spread operation involving all operand bits has to
be achieved. Many different circuit constructions for binary addition have been planned over the last decades,
covering a wide range of presentation characteristics. In today era, reversibility has become essential part of
digital world to make digital circuits more efficient. In this paper, we have proposed a new method to reduce
quantum cost for ripple carry adder and carry skip adder. The results are simulated in Xilinx by using VHDL
language.
LOW POWER AND HIGH SPEED DIVERSE DIGITAL CIRCUIT FOR SUB-THRESHOLD LEVELVIT-AP University
Day to day VLSI circuit is becoming more complex in regard of architecture and analysis point of view. A high
computation design with less power consumption and miniaturization in the area is implicit to the current semiconductor industry.
In these, a methodology for error-control parity generator and checker is fundamental of data communication and widely used in error control application. In this paper is the synthesis of the parity generator and checker, which has the unique architecture in terms of architecture complexity. Efficiency in terms of the VLSI performance attributes such as delay, power, and area. Then with the use of GDI technique a new architecture of parity generator and checker is introduced, we achieved a design with low supply voltage operation. The 3-bit parity generator and checker based on GDI technique is successful, simulated and tested at 0.5V, 1V, 1.5V, 2V supply voltage and consumed power at these voltages are 5μw, 2.5μw, 3.3μw and 0.2ns, 0.3ns, and 0.8ns worst condition of delay respectively.
Reducing the Number Of Transistors In Carry Select Adderpaperpublications3
Abstract: In existing method CMOS logic involved in carry select adder (CSLA), the data dependencies and redundant logic operations are analyzed and then reduced. The carry select (CS) operation is arranged before the calculation of-final-sum, which varies from the earlier methods. But the method is not much more efficient due to power consumption is high. This paper shows the comparison of CMOS logic design and modified Gate Diffusion Input logic (Mod-GDI) and proved Mod-GDI logic is more power-efficient than Gate Diffusion Input logic (GDI), Pass Transistor Logic (PTL) and CMOS logic design in CSLA. Basic GDI logic suffers from some limitations like swing degradation, fabrication difficulty in standard CMOS process and bulk connections. These limitations can be overcome by Mod- GDI. In the proposed scheme, Mod-GDI is better than GDI and CMOS in the maximum cases with respect to area, speed, and power dissipation, and power-delay products. From the simulation results, 45% reduction in power-delay product in Mod-GDI logic in CSLA is obtained. Mod-GDI technique performs varies logic functions by using two transistors. Mod-GDI logic is suitable for designing high speed and less power consumption with reduced number of transistors. Finally, we compare the power consumption and time delay of the existing method with our proposed scheme to show our achievement on accuracy.
This paper presents different techniques of one bit Full adder. In every technique the main requirements are power consumption, speed and power delay product. The proposed FIN-FET technique gives the bette.r power consumption, speed and power delay product than other techniques. The proposed Fin-FET technique is compared with some of the popular adders based on the power consumption, speed and power delay product. We designed each of these techniques by using Spice simulation soft wares.
In this paper it has been clarified that FinFET is a Fin Field effect transistor. It is promising substitute of CMOS in lower technology node. In this paper by making NAND Gate utilizing DG FinFET it is demonstrated that power utilization of IDDG FinFET is lesser than SDDG FinFET. At that point made an IDDG FinFET utilizing TCAD device and checked the impact of expanding the Fin width on the present qualities.

Multiple Valued Logic for Synthesis and Simulation of Digital CircuitsIJERA Editor
The Multiple valued logic(MVL) has increased attention in the last decades because of the possibility to represent the information with more than two discrete levels.Advancing from two-valued to four-valued logic provides a progressive approach. In new technologies, the most delay and power occurs in the connections between gates. When designing a function using MVL, we need fewer gates,which implies less number of connections, then less delay. In the existing system, the 4:1 multiplexer is designed using the MVL logic and various paramaters are analysed. In the proposed system, the idea of designing a Barrel shifter using the multiple valued logic and the parameters are all analyzed. All these designs are verified using Modelsim simulator.

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Abstract: In cmos design goals ,cmos technology provides better results than TTL(Transistor Transistor Logic
).but today due to increasing prominence of portable systems ,speed and low power designs are major issues in
high performance digital systems .flip-flops are basic storage elements used in all kind of digital systems. Flip
flops are widely used in memory elements, counters and registers also. And these circuits are used to
implementation of vlsi chips. So power consumption is the major concern in this which should be improved. This
paper proposes a a Design of single edge triggered low power d Flip Flop using GDI(Gate Diffusion Input
Technique).As a result using GDI power consumption is Reduced and features the best power delay product.
The operation of the D flip flop is analyzed and simulated using Tanner EDA .
Keywords- GDI Technique, negative edge triggered D flip flop, power, High speed.
I. Introduction
Now a day, with the increasing use of Mobile devices, laptops, consumer electronics demand a
stringent constraint on reducing power dissipation. Flip flops are the key elements used in sequential digital
systems. Flip flops and latches are the basic elements for storing information. Flip flop is one of the most power
consumption component. Flip flop is the most important state holding elements. Several flip flops was
researched and presented. In this paper an efficient technique is presented. .D flip flop is implemented using
GDI (Gate diffusion input )is introduced. Using GDI the main attention has been in improving the performance
of the circuit and reduced power delay product. There are two types of d flip flops are found in literature that are
single edge triggered and double edge triggered .but the double edge triggered flip flops suffers from
performance degradation, because it samples data on both clock edges. The single edge triggered flip-flops are
simple in design and sample data only one clock edge(either positive or Negative).These are mostly designed by
using master slave configuration.
II. GDI Function
Gate diffusion technique is defined as a new technique of low power digital combination of circuit
design. This allows reduced power consumption and delayed propogation.The GDI technique is more important
because it involves only two transistors. GDI technique can be used to design fast , low power circuits using
only few transistors and reduced power consumption ,delay and area of the digital circuit. It maintains low
complexity of logic design.GDI Technique is very flexible for digital circuits and power efficient using less
transistor count.GDI method is based on the simple cell. That is shown in figure .1. It contains four terminals, G
node, P node and N node are inputs and D node is output. G node is the common gate input of PMOS and
NMOS. P node is the outer diffusion node of PMOS.N node is the outer diffusion node of NMOS. D node is the
common diffusion of both transistors P, N,D may be used as input or output depends upon the structure
requirement.

It should be noted that the source of PMOS in GDI cell is not connected to VDD or source of NMOS is not
connected to GND. This feature gives the GDI cell two extra input pins to use to makes the GDI design more
flexible than conventional methods.
There are some functions that can be implemented by GDI Technique.
N P G D FUNCTION
‘0’ B A A*B F1
B 1 A A+B F2
‘1’ B A A+B OR
B O A AB AND
C B A AB+AC MUX
‘0’ 1 A A NOT
The advantage of GDI cell is the any logical functions can be implemented easily than other
conventional methods.
III. GDI Flip Flop Implementation
An implementation of low power negative edge triggered D flip flop using GDI (Gate Diffusion Input)
technique. The main aim of this work to minimize the power dissipation using GDI Technique. It is called Gate
Diffusion Input Technique because the inputs are directly diffused into the gates of the transistors of N type and
P type devices. This Negative edge triggered D flip flop is designed using Master slave configuration and both
contains four GDI cells, and the sampling is done on the falling edge of the clock signal. In this the input at the
falling edge is transferred to output port. Body gates and inverters are used in this circuit. Body gates used for
creating two alternative paths as for holding state or transparent state and inverters are used for buffering of the
internal signals for swing restoration .This circuit contains 18 transistors including inverters .so it is an efficient
alternative for low power consumption and better performance than conventional methods. Figure. 2 shows the
GDI D flip flop implementation circuit .

IV. Simulation Results
In this circuit implementation is done using L= 0.18u,w= 0.36u for NMOS and L= 0.18u, W= 0.72u for
PMOS .The circuit was simulated using 1.8 v for 180 nm technology. According to these values the simulation
output waveform for negative edge triggered D flip flop as shown below in figure.3.

Table.1- Simulation results for o.18um technology
The simulation results shows in Table .1. The power disipation reduced 40% then conventional
methods and it includes 18 transistors. Minimum power and delay produced by sizing, if transistor count less
than size is also small and power will be less consumed.
VI. Conclusion
In low power applications, power consumption and area are the main aspects to design over other
methods. So using GDI Technique power consumption is less than other methods and transistor count is also
less. This negative edge triggered D flip flop shows better performance and design is simulated using 180 nm
technology. It is suited for low power applications and used for high performance design.
