Design, Synthesis and Assessment of QCA primitives of 5-input Majority gate in field-coupled QCA Nanotechnology

Abstract

Quantum-dot Cellular Automata (QCA) is an exciting new development in the field of nanoscale-based very large scale integration (VLSI) that has the potential to replace more conventional complementary metal oxide semiconductor (CMOS) technology. In this article, a thorough and detailed description of the novel QCA based 5-input Majority gate is presented. In order to validate the accuracy of a 5-input majority gate, a comprehensive analysis has been carried out, taking into account the location of each and every QCA cell inside a structure. In this paper, a completely new 1-bit full-adder is constructed in order to assess the possible advantages offered by the recently developed 5-input majority gate. The comparative analysis with the reported designs in the literature revealed that the proposed full adder is superior in terms of cell count with a reduction of more than 54.79 %, as well as a decrease in area of more than 25 %, and a reduction in latency of 83.33 %. These findings were derived from the observation that the proposed full adder is better. For the purpose of demonstrating the usefulness and dependability of the strategy, power analysis have been carried out on the proposed full adder design using the QCAPro and QCADesigner 2.0.3 tools, respectively. The new majority gate technique is based on a variety of designs that enjoy the parameters of less area, durable circuit architecture, and optimal clock cycles, as well as the higher performance aspects associated with high-speed computation.
