A Comparative Analysis on Parameters of Different Adder Topologies (original) (raw)

Due to their widespread use in the effective implementation of fundamental binary arithmetic, adders are an essential component in digital integrated design. A basic adder topology unquestionably requires higher working speeds, tolerable power consumption, and significantly less chip area. An extensive comparative examination of many modern adder topologies is provided in the current paper. The in-depth analysis of the adder that is described in this paper aims to make it easier to choose an adder topology for any digital design while balancing the trade-offs between area, propagation delay, and power dissipation. In this paper, a thorough comparison of four distinct adder topologies-the Ripple Carry Adder, Carry Save Adder, Carry Skip Adder, and Carry Select Adder-is made on basis of a number of design metrics and performance factors.
