A novel nano‐scale architecture of Vedic multiplier using majority logic in quantum‐dot cellular automata technology

Abstract

Quantum-dot cellular automata (QCA) is a useful nano-scale technology that uses less space and energy than complementary metal oxide semiconductor (CMOS) for circuits designing. Innovative digital automation continually strives for increased density while consuming very little power. QCA, which is based on Coulomb repulsion, is one of the most recent nanotechnologies. On the other hand, derived computing could serve as a useful prototype for energy-efficient nano-scale layouts. A multiplier is an important component of various digital circuits. On the basis of QCA, promising nanotechnology, a high-speed and simple multiplier is constructed in this study. This research focuses on multiplier designs based on two-bit Vedic multiplier mathematics. The authors use the QCADesigner-E modelling environment to develop an ultra-efficient and less complicated two-bit Vedic multiplier with the assistance of the majority gate for low-energy and high-speed nanotechnology applications. Compared with other current structures, the suggested architecture has a reduced cell count and area. Furthermore, simulation findings showed that the suggested design is long-term viable and may be utilized to implement complicated circuit designs for nano-communication networks.
