A Novel Reversible EX-NOR SV Gate and Its Application

Conference paper
Part of the Lecture Notes in Networks and Systems book series (LNNS, volume 5)


Reversible logic in quantum computing and nanotechnology provides solution to optimize the power and this technology can be put into use in a variety of low power applications such as optical computing, and CMOS VLSI design. An EXNOR gate is a digital logic gate that can be used as an equivalence gate and also in variety of applications. A new reversible SV gate is proposed in this paper that functions as an EXNOR gate and whose quantum cost is 1. An equivalence checker also has been designed in this paper that can be used to check the equivalence of two n-bit binary numbers. The proposed SV gate has been validated by comparing its performance with some of the existing circuits in literature. The results prove to be more reliable, efficient and provide a basis for building more complex arithmetic systems using the concept of reversible logic that can be used in digital data transmission circuits.
