摘要

量子点元胞自动机(QCA)技术是替代CMOS技术的一种很有前途的纳米级技术。在数字电路中，多路复用器是最重要的部件之一。在本研究中，提出了一种高效的单层2到1 QCA多路复用电路，采用多数门和逆变门。此外，高效的4对1和8对1 QCA多路复用电路使用该2对1多路复用电路实现。所开发的多路复用电路在qcaddesigner工具中实现。结果表明，所开发的2对1、4对1和8对1多路复用器电路使用了16 (0.01?m2)、96 (0.11?m2)和286 (0.43?m2) QCA单元(面积)。结果表明，与现有的多路复用器电路相比，所提出的8比1多路复用器电路的成本降低了约25%- 99%。

Design of novel multiplexer circuits in QCA nanocomputing

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.
