Design and simulation of new XOR gate and code converters using Quantum Dot Cellular Automata with reduced number of wire crossings

Quantum Dot Cellular Automata is one of the six emerging technology which can overcome the limitations of current transistor based technology. Quantum Dot Cellular Automata is popular technology due to its extremely small feature size and ultra low power consumption. In this paper new XOR gate using Coupled Majority Voter Minority gate is proposed. Using this proposed XOR gate Binary to Gray Code and Gray to Binary Code Converters are designed. This paper shows the performance analysis of Proposed XOR circuit and it has been proved that XOR gate and Binary to Gray and Gray to Binary Code converters are efficient in terms of area, complexity, latency and wire crossings. QCADesigner 2.0.3 tool is used for design and simulation of these circuits.
