Robust Multiplexer Design and Analysis Using Quantum Dot Cellular Automata

Quantum Dot Cellular Automata (QCA) is an alternate version of the existing conventional CMOS technology due to its low power intake, faster speed, and smaller size. A multiplexer is a very important logical block in VLSI designs. In this paper, a 2:1 multiplexer (MUX) architecture is proposed, analyzed and compared with related existing architectures. The kink energy of proposed circuit has been calculated and hazard analysis has been completed successfully. All designs in this paper are simulated, checked, and verified using the popular QCADesigner tool. The comparisons of the proposed design with respect to different parameters of the existing MUX(s) along with their corresponding graphical representations prove the robustness of the proposed multiplexer.
