Low-Power Multiplexer Structures Targeting Efficient QCA Nanotechnology Circuit Designs

Quantum-dot cellular automata (QCA) technology is considered to be a possible alternative for circuit implementation in terms of energy efficiency, integration density and switching frequency. Multiplexer (MUX) can suitable candidate designing QCA circuits. In this paper, two different structures energy-efficient 2×1 MUX designs are proposed. These MUXes outperform the best existing design power consumption with approximate reductions 26% 35%. Moreover, similar or better performance factors such as area latency achieved compared available designs. used fundamental building blocks replacing majority-based QCA. The scalability property proposed excellent complex
