Abstract

Abstract: Quantum-dot Cellular Automata (QCA) is a promising transistor-less nanotechnology that is used for designing digital circuits at nano dimensions. Its major advantage is that QCA enables the circuits to operate at faster rates compared to CMOS. Any large digital circuit application uses full adder as a basic component. Many researchers have designed full adders with different number of quantum cells, in various sizes and layers and different delays. This paper presents a detailed report of all existing full adders designed using QCA. A comparison of full adder designs is carried out to identify the better one. Simulation and analysis of existing QCA designed full adders is performed using QCADesigner tool.
