ResumoQuantum dot cellular automaton (QCA) are dominant nanotechnology which has been used extensively in digital circuits and systems. It is a promising alternative to complementary metal–oxide–semiconductor (CMOS) technology with many enticing features such as high-speed, low power consumption and higher switching frequency than transistor based technology. The code converters are the basic unit for transformation of data to execute arithmetic processes. In this paper, QCA based 2-bit binary-to- gray; 3-bit binary-to-gray and 4-bit binary-to-gray code converter have been proposed. The proposed design reduces the number of cells, area and raises switching speed. The simulations are completed using QCADesigner and Microwindlite tool which is widely used for simulation and verification.
