Binary to Gray Code Converter Implementation using QCA

Quantum dot Cellular Automata (QCA) is a nanotechnology which offers an attractive solution to overcome the physical limits that CMOS devices faces during further downscaling of their dimensional sizes. In QCA, the electrons are basically restrained in quantum dots. The fundamental basic gates in QCA are the Majority Gate (MG) and the Inverter. Further downscaling of the dimensions of CMOS devices is more and more challenging, as reduction in feature size of CMOS devices has reached to its feature size limit. So we use QCA which provides powerful features such as higher packaging density, reduced area, much lower power dissipation and higher switching speeds at nanometer scale. QCA designs new logic circuits which are translations of standard logic devices. Here in this paper we proposed QCA implementation of binary to gray code converter.
