Abstract

Abstract:

The reversible logic is found to be very useful in fields of low power digital circuits and quantum computers due to its feature of ultra low power consumption. A new reversible logic gate (NRG) is proposed in this paper, which can perform majority computation, Exclusive-OR and Inclusive-OR operations. The proposed NRG is realized by quantum-dot cellular automata (QCA) technology, and reversible QCA adder circuits are designed with the proposed NRG. Simulation results with the QCA Designer tool indicate that the proposed NRG and reversible adder circuits perform well. Moreover, the reversible adder with the NRG requires fewer gates, while generating fewer garbage outputs.

Key words: reversible logic, quantum-dot cellular automata, adder, majority gate
