A Novel Design “Binary to Gray Converter” with QCA Nanotechnology

Abstract

Quantum dot Cellular Automata (QCA) is a new direction in creating logic circuits based on
nanotechnology.It is a promising alternative to CMOS technology with many appealing features such as high speed,
lowpower consumption and higher switching frequency than transistor basedtechnology.The code converters are the
basic unit for alteringof datato perform arithmetic processes. In this paper, QCA based3-bit binary to gray and 4-bit
binary to gray code converter, with a minimum number of cells, has beenproposed.The simulations are completed using
QCA Designer.
