Abstract Quantum-dot Cellular Automata (QCA) technology is believed to be a good alternative to CMOS technology. This nanoscale technology can provide a platform for design and implementation of high performance and power efficient logic circuits. However, the fabrication of QCA circuits is susceptible to faults appearing in this form of missing cells, additional cells, rotated cells, and displaced cells. Over the years, several solutions have been proposed to address these problems. This paper presents a new solution for improving the fault tolerance of three input majority gate. The proposed majority gate is then used to design 2-1 multiplexer and 4-1 multiplexer. The proposed designs are implemented in QCA Designer. Simulation results demonstrate significant improvements in terms of fault tolerance and area requirement.
