Novel Code Converters Based On Quantum-dot Cellular Automata (QCA)
Firdous Ahmad  | GM Bhat
Abstract: Quantum-dot cellular automata (QCA) is an emerging nanotechnology and a possible alternative for complementary metal-oxide semiconductor (CMOS). In this paper; we have proposed novel XOR gates. The models are suitable for designing combinational circuits with less area and circuit complexity. Code converters like excess-3 code; gray code; parity code generator; and checker; with minimum area and circuit complexity have been attempted by using proposed XOR gates. The novel designs enjoy the features of small area; superior performance factors in respect of area; latency; circuit stability; and low power dissipation. The operation of QCA circuit is simulated using QCADesigner tool.
