Low-Power Multiplexer Structures Targeting Efficient QCA Nanotechnology Circuit Designs

In In this project, two different structures of 2  1 MUX designs are proposed using QCA cell QCA technology is considered to be a possible alternative for circuit design. implementation in terms of energy efficiency, integration density and switching which can replace CMOS implementations as nm technology decreases. Multiplexers (MUX) can be considered to be suitable candidates for designing QCA circuits.

The The proposed MUX outperforms the best existing design in terms of power consumption. with approximate reductions. Moreover, similar or better performance factors in Area and latency are achieved compared to the available designs. These MUX structures can be used as fundamental energy-efficient building blocks for replacing the majority-based structures in QCA. The scalability property of the The proposed MUX are excellent and can be used for energy-efficient complexes. QCA circuit designs. These implemented designs are simulated and waveforms are observed using the QCA designer tool.
