Comparative Study of Transistor Logic Families in Half Adder Circuit Design

Also Available Domains Nano Technology|Transistor Logic

Project Code :TVMABE357

Objective

The objective of this project is to design a half adder circuit using various transistor logic families and conduct a comparative study of their performance. It focuses on evaluating parameters such as speed, power consumption, propagation delay, and circuit area for different logic families including CMOS, PTL, and Domino logic. The designs will be simulated and verified to ensure correct functionality and to measure performance accurately. Comparative analysis will highlight the strengths and limitations of each logic family in arithmetic circuit design. The overall goal is to determine the most efficient and reliable logic family for high-performance digital circuits.

Abstract

Abstract:

This work analyses the half-adder circuit in different transistor logic families such as CMOS, Psuedo nMOS, Transmission Gate, Pass Transistor, Dynamic CMOS and Domino CMOS logics for area in terms of transistors count, power consumption and time delays. The simulation results show that the listed transistor families are the most efficient and highlighting on advantages and disadvantages of each transistor family. These analyses are done by using Tanner EDA environment. For lower area and power consumption Pass Transistor logic can be implemented, occupying 40% of the workspace in comparison with Complementary MOS design style. For higher speeds applications Domino or Dynamic CMOS Logics are suitable and consume less power.
