This document discusses design rules for analog circuit printed circuit boards (PCBs). It outlines three major factors: 1) component placing, 2) signal conductors, and 3) supply and ground conductors. For component placing, it recommends arranging components for access, adjustment, and heat dissipation. For signal conductors, it advises keeping lengths short to minimize interference and carefully laying out high frequency, feedback, and high gain circuits. For supply and ground conductors, it suggests keeping them independent for analog and digital circuits and reference voltages.
Single Stage Differential Folded Cascode AmplifierAalay Kapadia
The purpose of this project is to design a single-stage differential input and single-ended output) Amplifier. 0.35-um CMOS process and a supply voltage of 1.8 V is required in this design. The desired specifications is given. Among the single-stage topologies, the folded-cascade topology is chosen to meet the requirement for a high output swing design.
Introducing higher dielectric constant (k > 10) insulators [mainly transition metal (TM) oxides] is therefore indispensable for the 70 nm technology node and beyond
TM silicates such as HfSiOx have been preferred because they have better thermal stability compared to their oxides. The dielectric constant of TM silicates is less than TM oxides but higher than silicon oxide.
This presentation describes to you the very basic introduction of PN junction diode. All the topics and contents are presented in such a manner that students can understand it very easily and prepare it for final exam. At the end of this presentation, a few multiple choice questions (MCQ) are also there to test your knowledge on a particular topic that would be discussed in presentation.

The performance obtainable from a single-stage amplifier is often insufficient for many applications, hence several stages may be combined forming a multistage amplifier. These stages are connected in cascade, i.e. output of the first stage is connected to form input of second stage, whose output becomes input of third stage, and so on.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

1. Design Rules For Analog Circuit PCB
Presented By:-
Shovana Khan Yusufzai
M.Tech in E.D&T
NIELIT, Gorakhpur
2. Major Factors in Designing Analog Circuit PCB
• 1 Component Placing
• 2 Signal Conductors
• 3 Supply and Ground Conductors
3. 1. Component Placing
• Components which need access from the front plate
have to be exactly according to the instructions of the
equipment designer.
• Components for internal adjustment such as,
potentiometer , trimmer, switches etc have to be
arranged near the board edge and oriented in the proper
direction.
• Component with metal case should not be placed very
near to the access path that is needed for adjustment of
screw driver other wise short circuit may occur.
4. • Heat producing components are regularly distributed
over the entire board area, as far as it is feasible. This is
to avoid a locally overheated board.
• Hot components have to be separated from the board
surface by suitable surfacers.
• The locating of heat sensitive components must avoid a
close proximity to hot components as well as a place in a
flow of already warmed up air.
5. 2. Signal Conductors
• Signal Conductors in analog circuit PCBs have to fulfill a
variety of different tasks, e.g. input, reference level,
feedback, output, etc.
• The length of any signal conductor should be made as
short as possible.This is because the magnitude of the
undesired inductive and capacitive coupling effects
increases more or less proportionally to the length of the
particular conductor.
• Apart from making of a good PCB, there are also other
techniques such as shielding or guarding with metallic
enclosures which have to be employed for a satisfactory
operation of equipment.
6. The signal conductor layout has to be done
particularly carefully for the following type of
circuits:
2.1 High Frequency Amplifiers/oscillators:
• At higher frequencies and with a long voltage supply line,
the circuit may oscillate because the voltage gain in an
emitter follower can be high i.e.,
Gain= Zcollector/Zemitter
• For precaution a capacitor is placed between the collector
and ground.
7. • And in case of oscillator similar problem occurs ,so to
avoid this, the layout has to be carefully made in order to
reduce the capacitive coupling.
8. • An improper layout of a high frequency
amplifier can also result in a reduced
bandwidth of the amplifier. If the input and
output conductors are close to each other ,
there can be a feedback resulting in
oscillations.
10. • If the ground and voltage conductors are long , a large
current I drawn by the high-power stage will flow through
the conductors with their own resistivity R.
• This additional resistance can modulate the Vcc and
GND of the input stage resulting in low frequency
oscillations which is called motorboating effect.
• To overcome this effect decoupling of the power supply
conductors with sufficiently large capacitor must be
done.
• Also separate Vcc and GND conductors can be provided
for two different stages.
11. 2.3 Feedback Amplifiers
• In designing high-wattage power supplies considerable
care in PCB layout design as well as in planning of the
remote sensing line to the front panel is necessary to
meet the regulation factor.
• A star grounding technique is used for the feedback
amplifier PCBs. The rectifier/capacitor circuit must be
connected to the star point for good cicuit performance.
12.
13. 2.4 High Gain DC Amplifiers(Thermal
Effects):
• When a device(transistor, DC amplifier) is soldered onto
the PCB, a thermocouple junction is formed between
copper( i.e. PCB conductor) and the kovar lead of the
transistor.
• If a temperature gradient exists, then different junctions
will create different voltages, thus effecting a noisy signal
to the amplifier.
14. 2.5 Amplifier handling low level signals
a) Low level, high impedance:
Due to high impedance the capacitive coupling occurs . For
reducing the coupling , it is necessary to provide
sufficient distance between the high impedance
conductors and other interfering signal lines.
b) Low level, low Impedance:
If the impedance is low one has to be careful about induced
voltage due to magnetic fields or inductive coupling.
15. 3. Supply and Ground Conductors
3.1 Ground Lines
• Analog and digital circuits on the
same PCB should strictly have
independent ground conductor
networks.
• There is one more type of circuit
part which should be provided with
separate ground conductors:
Reference voltage circuits. These
are sensitive to ground potential
fluctuations because the
difference voltage between an
input and reference is mostly
amplified and or used to drive a
switching device.
16. 3.2 Supply Lines
• Supply lines have to be provided with sufficient width to
keep resistance and inductivity low.
• Supply lines are connceted to the circuit end with the
highest signal power level.
• Reference voltage circuits should tap with the supply
lines directly at the input to the PCB.
