Title: Low power CMOS parallel prefix adders
Authors: Yang, Shaochen

Abstract: Addition is the basic operation in many modern electronic applications. As the fastest adder, parallel prefix adder is of most interest for many circuit designers. For the past few decades, supply voltage and the size of transistors have been reduced tremendously. With more and more transistors being integrated on one single chip, the power issue must be taken care of. Low power adder has been studied for years and many solutions are proposed. In this paper, a new circuit is designed at transistor level. The proposed circuit cells adopt transmission gate logic and develop a MUXbased structure. Simulations are conducted using Cadence. The result shows that the new adder demonstrates a better performance in terms of power dissipation. It saves more than 30% energy in all the adders with different word length.
