This paper describes the comparison between the hybrid adders. Adders are always used in many data-processing systems to perform fast arithmetic operations. The carry select adder (CSA) is a high speed adder. It provides good compromise between RCA and CLA. The ripple carry adder (RCA) has a most compact design but it takes longer computation time. The time critical applications uses carry look-ahead adder (CLA) to derive fast result but it required a large area. In this work we compared hybrid adders on the basis of delay, power and area. This design has been synthesized by Spartan 3 family with XC3S400 device.
