Study of Existing Combination Circuits using CMOS and QCA Technology to Compare Their Efficacy

Abstract

The potential limitations on the future advancement of microelectronics regular circuit scaling may arise from high power consumption and design intricacy. Therefore, it is imperative to introduce elective innovation to enhance future designs. The utilization of QCA for combinational circuit implementation represents a cutting-edge technological advancement that aims to address the scaling challenges faced by modern electronic devices. The circuit is characterized by the configuration of quantum cells in this logic design technique. This technique relies on the concept of computing through a field connection The utilization of QCA offers many benefits, such as reduced spatial requirements, elimination of interconnects, increased clock frequency, and the potential for low-power processing due to the absence of electron movement. This paper offers a comprehensive comparative analysis of various combinational circuits such as Full adder, MUX, XOR etc. that are considered essential in the field, by utilizing CMOS innovation and QCA nanotechnology.
