Low Power Implementation of Sequential Circuits using Reversible Logic Gates

Abstract

In the recent years, reversible logic has emerged as a promising technology having its applications in low power CMOS, quantum computing, nano technology and optical computing. Reversible logic circuits provide low power dissipation as well as distinct output assignment for each distinct input. The classical gates such as the NAND, AND, NOR, OR, XOR and XNOR are not reversible. This paper demonstrates the reversible logic synthesis Oof sequential circuits. The circuit is designed using only reversible NOT gate, AND/NAND gate, OR/NOR gate and XOR gate. The proposed sequential circuits have been simulated in tanner. The comparative results show that the proposed design is much better in terms of power.
