The key components in digital design are Half adders.They perform not only addition operations, but also many other functions such as subtraction, multiplication and division. Very Large-Scale Integrated circuits (VLSI) frequently requires adders of various bit widths from processors to Application Specific Integrated Circuits (ASICs). Recently reported logic style comparisons based on full-adder circuits claims that the Complementary Pass transistor Logic (CPL) is much more power-efficient than complementarymetal oxide semiconductor(CMOS). However, new comparisons are performed on more efficient (CMOS) circuit realizations and a wider range of different logic cells as well as the use of realistic circuit arrangements demonstrates that the (CMOS) is superior to (CPL) in most cases with respect to speed, area, power dissipation, and power-delay products. Even Adder designed using (CMOS) complementary metal oxide semiconductor technology can have more power as well as speed than that using (CMOS) technology. The most important and widely accepted matrices for measuring the quality of adder designs power dissipation,propagation delay, and area. The overall performance can be significantly improved by using arithmetic circuits. This paper describes the comparative performance of half adder designed using TANNER (EDA) Electronic Design Automation, using different (CMOS) logic design styles.
