Quantum-dot Cellular Automata (QCA) technology is a promising alternative nano-scale technology for CMOS technology. In digital circuits, a multiplexer is one of the most important components. In this study, an efficient and single layer 2 to 1 QCA multiplexer circuit is proposed using majority gate and inverter gate. In addition, efficient 4 to 1 and 8 to 1 QCA multiplexer circuits are implemented using this 2 to 1 multiplexer circuit. The developed multiplexer circuits are implemented in QCADesigner tool. According to the results, the developed 2 to 1, 4 to 1, and 8 to 1 multiplexer circuits utilize 16 (0.01?m2), 96 (0.11?m2), and 286 (0.43?m2) QCA cell (area). The results demonstrate that the proposed 8 to 1 multiplexer circuit reduces the cost by about 25%- 99% compared to the existing multiplexer circuits.
