Design of reversible multiplexer 4*1 by multiplexer 2*1 in the quantum cellular automata (QCA) circuits

Abstract

Quantum cellular automata (QCA) circuits are an alternative CMOS technology. Also, given the growing importance of reducing energy consumption, the plan of use reversible logic in QCA technology is a new issue, which reduces power dissipation in circuits.

In this paper, a reversible multiplexer 4*1 circuit was designed, and this multiplexer is simulated using the QCA Designer software. Therefore, according to its reversibility, power consumption was reduced, and by error tolerance mechanisms, a bit error is prevented.
