A Novel Full Comparator Design Based on Quantum-Dot Cellular Automata

Davoud Bahrepour
Abstract— A lot of research has been done for implementing digital systems at nano-scale level. A quantum-dot cellular automaton (QCA) is a promising as well as emerging technology for implementing digital systems at nano-scale. QCA have attracted a lot of attention because of its extremely small feature size (at the molecular or even atomic scale) and its ultra-low power consumption, making it one candidate for replacing CMOS technology. This technology has been studied from a variety of physical and chemical aspects and in this paper, a novel full comparator design is introduced as a digital logic application for QCA-based circuits. Comparator is one of the important components in digital logic design and it widely used in central processing units (CPUs). The proposed design is compared with previous works in terms of area and delay. Comparisons show that the proposed design has improvement in area and delay.

Index Terms— Full comparator, half comparator, quantum-dot cellular automata, nano-scale circuits.
