An Optimal Design of Odd Parity Generator by Using Five Input Majority Gate in Quantum Dot Cellular Automata
Abstract
Odd parity generator is a device that generates a parity bit which when added to a string of binary code ensures that the total number of 1-bits in the string is odd. In this project, a novel effective design of odd parity generator is proposed by the use of majority gate and simple inverter. The QCA 3-bit odd parity generator outshines in terms of cell count area and delay. The number of cells in QCA circuits is similar to the number of transistors in CMOS circuits. The design is made effective by reducing QCA wire crossings and cell count. The main objective is to reduce the size of the circuit and to improve the speed of operation of QCA circuits. The proposed 3-bit odd parity generator shows the desired result. The design is simulated using QCA Designer 2.0.3 which gives efficient output
