Analysis of different Adders using CMOS, CPL and DPL logic

Abstract

In this paper we design and analyse different types of adders using CMOS, Complementary Pass Transistor Logic(CPL), Double Pass Transistor Logic(DPL) logics. Ripple Carry Adder, Carry Look Ahead Adder, Carry Save Adder, Carry Incremental Adder, Carry Skip Adder, Carry Select Adder, Conditional Sum Adder are designed using CMOS, Complementary Pass Transistor Logic(CPL), Double pass transistor logic(DPL) logics for 16-bit, 32-bit and their speed, area and power are compared.
