Comparative Analysis of Adders

Sakshi Gaur

In digital circuits, an adder is the most common block used to perform addition of numbers or bits. Adder can be implemented as half adder or full adder, depending on the requirement. In this paper, one bit static full adder schematic is generated (along with its layout using tool Mentor Graphics Hep 1) and is simulated for transient analysis and then this as component is used to implement different types of four bit adders like Ripple carry adder, Carry select adder, By pass adder and Carry look ahead adder. Transient analysis for the same is done along with comparison of these adders based on parameters like power dissipation, delay, no. of gates and average no. of logic transitions and finally the conclusion is drawn.

Keywords: Ripple carry adder, Carry select adder, By pass adder, Carry look ahead adder, Power dissipation, Delay, No of gates
