Five-Input Complex Gate using Quantum Dot Cellular Automata

Tina Suratkar

This paper presents the basics of quantum dot cellular automata along with the QCA logic devices such as the QCA wire, inverter and the majority gate. The four phases of the clocking have been discussed and also the implementations of the complex gate have been done using the QCADesigner tool. The logical structures such as AND and OR gates using a quantum dot cellular automata 3-input majority gate have been discussed based on which the five-input complex gate have been designed and can be configured into logical structures such as four input AND and OR.
