In this paper, a comparative study in terms of design and performance of 8-Bit Ripple Carry Adder (8B RCA) using CMOS circuits, pass transistors and Transmission gates is presented. 1-bit ripple carry adders are used as a base to design 8-bit ripple carry adders then the schematic designs for all the three configurations are further converted into fabrication layouts. Simulation of the schematic designs is carried out to check the logic operations. In the end, performance analysis with respect to power dissipation of layout designs is performed.
