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.
