A Novel Architecture for Quantum-Dot Cellular Automata Multiplexer
Quantum-dot Cellular Automata (QCA) technology is attractive due to its low power consumption, fast speed and small dimension; therefore it is a promising alternative to CMOS technology. Additionally, multiplexer is a useful part in many important circuits. In this paper we propose a novel design of 2:1 MUX in QCA. Moreover, a 4:1 multiplexer, an XOR gate and a latch are proposed based on our 2:1 multiplexer design. The simulation results have been verified using the QCADesigner.
