Design of Improved 8:1 Multiplexer u sing Quantum dot Cellular Automata Technology

Abstract

A much-required breakthrough in the field of VLSI took place with the birth of Quantum-dot cellular automata (QCA) technology, an impressive amalgamation of Quantum Physics and Nanotechnology and acted as a possible replacement to the age-old semiconductor transistor-based de- signs (CMOS) with Boolean paradigm. In this paper, we aim at implementing this technology to build a robust 8:1 multiplexer that can help in building and developing many more digital logic circuits, from an already proposed 2:1 multiplexer. It has excellent efficiency with respect to least cell count, latency, space and power dissipation.
