摘      要：Quantum dot cellular automata(QCA)technology is emerging as a future technology which designs the digital circuits at quantum *** tech-nology has gained popularity in terms of designing digital circuits,which occupy very less area and less power dissipation in comparison to the present comple-mentary metal oxide semiconductor(CMOS)*** designing the rou-ters at quantum levels with non-blocking capabilities various multi-stage networks have been *** manuscript presents the design of the N×NClos switch matrix as a multistage interconnecting network using quantum-dot cellular automata *** design of the Clos switch matrix presented in the article uses three input majority gates(MG).To design the 4×4 Clos switch matrix,a basic 2×2 switch architecture has been proposed as a basic *** 2×2 switching matrix(SM)design presented in the manuscript utilizes three input majority ***,the 2×2 SM has been proposed usingfive input majority *** different approaches(1&2)have been presented for designing 2×2 SM usingfive input majority *** 2×2 SM design based on three input majority gate utilizes four zone clocking scheme to allow signal ***,the clocking scheme used in 2×2 SM using three input MG and in 2×2 SM approach 1 usingfive input MG is *** 2×2 SM approach 2 design,utilizes the clocking scheme in which clocks can be applied by electricfield generators easily and in turn the switch element becomes physically *** simulation results conclude that the 2×2 SM is suitable for designing a 4×4 Clos network.A higher order of input-output switching matrix,supporting more number of users can utilize the proposed designs.
