Implementation of Novel 2x2 Vedic Multiplier using QCA Technology

Abstract

Advantages like working at high speed, scalability, and lower power consumption make QCA technology more feasible than modern CMOS technology. QCA Technology uses electrons’ Coulombic interaction and polarization to represent binary information 0 and 1. The present paper proposes a novel XOR Gate and a Half Adder design and uses them to implement a new 2x2 Vedic Multiplier on QCA technology. A 2x2 Vedic Multiplier multiplies two inputs, of two bits each, using Urdhva-Tiryakbhyam Vedic Sutra. The proposed circuit has a reduced cell count and Quantum cost compared Co-planar Vedic Multipliers to available in the literature. QCADesigner 2.0.3 is used for the simulation and verification of all three proposed circuits.
