Introduction to Reversible Logic Gates & Its Application

Abstract

In current scenario, the reversible logic design attracting more interest due to its low power consumption. Reversible logic is very important in low-power circuit design. The important reversible gates used for reversible logic synthesis are Feynman Gate, Fredkin gate, toffoli gate, New Gate sayem gate and peres gate etc. This paper present a basic reversible gate to build more complicated circuits which can be implemented in ALU, some sequential circuits as well as in some combinational circuits. It also gives brief idea to build adder circuits using the basic reversible gate like peres gate and TSG gate.
