Designing State Machine
The document discusses designing state machines using state diagrams. It describes a state machine to control tail lights on a 1965 Ford Thunderbird with three lights on each side. The state machine has three inputs (left turn, right turn, hazard) and six outputs. It provides steps to design the state diagram, including ensuring it is mutually exclusive and all inclusive. It also describes techniques for synthesizing the state machine using a transition list, including writing transition equations and excitation equations.

encoder and decoder in digital electronics
In digital electronics, a decoder can take the form of a multiple-input, multiple-output logic circuit that converts coded inputs into coded outputs, where the input and output codes are different e.g. n-to-2n , binary-coded decimal decoders. Decoding is necessary in applications such as data multiplexing, 7 segment display and memory address decoding.
An encoder is a device, circuit, transducer, software program, algorithm or person that converts information from one format or code to another. The purpose of encoder is standardization, speed, secrecy, security, or saving space by shrinking size. Encoders are combinational logic circuits and they are exactly opposite of decoders. They accept one or more inputs and generate a multibit output code.

Noise Analysis of Trans-impedance Amplifier (TIA) in Variety Op Amp for use i...
VLC is a complex system with lots of challenges in its implementation. One of its problems is noise that originated from internal and external sources (sunlight, artificial light, etc). Internal noise is originated from active components of analog front-end (AFE) circuit, which will be discussed in this paper, especially on the trans-impedance amplifier (TIA) domain. The noise characteristics of AFE circuit in VLC system has been analyzed using the variety of available commercial Op Amp and different types of the photodiode (Si, Si-PIN, Si APD). The approach of this research is based on analytical calculus and simulation using MATLAB®. The results of this research show that the main factor that affecting the noise is e , the feedback resistor (R f ), and junction capacitor in the photodiode (C ). Besides that, the design concept of multi channel TIA (8 channel) using IC Op Amp, with consideration of pin number of each Op Amp, supply needs, the initial value of R f , converter to 8-DIP and feedback capacitor (C f j ) channel, also discussed in this paper.
SRAM DRAM
This document is a presentation on RAM that was presented by Tipu Sultan and Md Shakhawat Hossain Sujon to Tafisr Ahmed Khan. It summarizes the key differences between SRAM and DRAM. SRAM does not require refresh cycles but is more expensive and slower than DRAM. A typical SRAM cell uses 6 transistors arranged in two cross-coupled inverters, while a DRAM cell uses one transistor and one capacitor. DRAM must perform periodic refresh cycles to maintain its data due to capacitor leakage, whereas SRAM maintains its data statically without refresh.

It then discusses the main types of transistors - BJT and FET, including MOSFET and JFET. The rest of the document focuses on MOSFETs, explaining what they are, their terminals and symbols, types of MOSFETs like n-MOSFET and p-MOSFET, and how MOSFETs work and are fabricated through processes like photolithography, etching, diffusion, and oxidation.

3.bipolar junction transistor (bjt)
Bipolar junction transistors (BJTs) are three-terminal semiconductor devices consisting of two pn junctions. There are two types, NPN and PNP, depending on the order of doping. BJTs can operate as amplifiers and switches by controlling the flow of majority charge carriers through the base terminal. Proper biasing is required to operate the transistor in its active region between cutoff and saturation. Common configurations include common-base, common-emitter, and common-collector, each with different input and output characteristics. Maximum ratings like power dissipation and voltages must be considered for circuit design and temperature derating.
Mosfet
A MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a semiconductor device that is commonly used in power electronics. It works by modulating charge concentration between a gate electrode, which is insulated from other device regions by an oxide layer, and a body region. Depending on whether it is an n-channel or p-channel MOSFET, the source and drain regions have either n+ or p+ doping while the body has the opposite doping. Applying a voltage to the gate can turn the channel between source and drain on or off to allow or prevent current flow. MOSFETs can be made with silicon on insulator or other semiconductor materials.
Metal Oxide Semiconductor Fet (Mosfet)
The document discusses different types of field effect transistors (FETs), including junction FETs (JFETs), metal-oxide-semiconductor FETs (MOSFETs), and metal-semiconductor FETs (MESFETs). It focuses on the structure and operation of n-channel and p-channel MOSFETs, describing how a positive or negative gate voltage is used to create a conducting channel. Scaling challenges for MOSFETs are also discussed, along with new materials needed like high-k dielectrics and metal gates, and approaches like silicon-on-insulator (SOI) technology.
