Design and Evaluation of a Majority Gate Based Encoder in Quantum-dot Cellular Automata (QCA)

Abstract

Quantum-dot cellular automata are the rising nanotechnology used to structure the nano
scale circuits. QCA is the powerful elective technique to the CMOS innovation. In this
paper,anovel effective design of encoder is proposed by the use of Majority gate and
inverter.The proposed QCA encoder 4X2 and8X3 design outshines interms of cell count, area
and delay. The number of cells in QCA circuits is similar to the number of transistors in
CMOS circuits. The structure is made successful by diminishing QCA wire intersection and
cell. The fundamental goal is to diminish the measure of the circuit and to enhance the speed
of activity of QCA circuits.
