Optimal Design of a Reversible Full Adder
Yvan Van Rentergem and Alexis De Vos

Four designs for reversible full-adder circuits are presented. The implementation of these logic circuits into electronic circuitry is based on c-MOS technology and pass-transistor design. In particular, we investigate the use of the fundamental building block of Fredkin. We present a chip containing three different reversible full adders.
