Abstract

Scaling down trend of CMOS transistor is approaching its lowest point, the rational substitute for the CMOS technology to attain advance improvements in terms of size, low power, and device density...

Highlights

CMOS technology has been emerged over the last four decades as a predominant technology of microelectronic
Quantum dots are small nano metric size (2–10 nm) composed of semiconductor elements. Their small size denotes that electrons do not have to move as far as equated with higher particles, so electronic tools conceived by quantum dots can perform swifter (Abdullah-Al-Shafi, 2016a; Arqub, 2015; Bahar, Abdullah-Al-Shafi, & Bhuiyan, 2017)
This study proposes the novel and competent Quantum-dot Cellular Automata (QCA) multiplexer, decoder, nano-communication circuit and a reversible D flip-flop using QCA technology

Summary

Introduction

CMOS technology has been emerged over the last four decades as a predominant technology of microelectronic. QCA clocking mechanism To form more complicated QCA devices, the location of QCA cell is essential needs to coordinate the information, so that evade having a signal extending a logic gate and proliferating before the other inputs move the gate This specific characteristic is imperative in QCA circuits, ensuring its accurate function and this aspect are attained by QCA clock. Switch Hold Release Relax a group of QCA cells to construct a particular calculation and its positions are stationary and its outputs can be applied as inputs to the following clock zone. The QCA layout of the proposed decoder circuit is shown in Figure 3(a) using four majority voters and three inverters.
