Quantum Dot Cellular automata, one of the emerging nanotechnology is the possible alternative to these problems. This paper presents the comparative analysis of various QCA methodologies used for the implementation of full adder circuit. Also the designs and performance analysis of QCA full adder using Majority gate, minority gate, multilayer wire crossing, 5 input Majority voter gate is discussed. The designs follow the conventional design approaches, but due to the technology differences, they are modified for the best performance in QCA. The layout and simulation results are presented using QCADesigner Tool. QCADesigner is a QCA layout and simulation tool developed at the University of Calgary [1]. Simulations indicate very attractive performance regarding complexity, area, and delay in Minority gate based full adder and 5 input MV gate based full adder.
