An efficient Design of 1:2 Demultiplexer Based on QCA technology

Abstract

Quantum-dot cellular automata (QCA) offers significant area reduction due to nano-size, high operational speed with significantly low power levels. It is a wireless technology and does not use current or voltage to carry information. Instead, it utilizes the positioning of the electrons. In this paper, an optimal 1:2 demultiplexer based on QCA technology has been investigated. QCAPro software has been used to estimated the energy dissipation of the suggested design. Simulation is achieved for the suggested design using QCADesigner software. The proposed design has less number of cells, area and energy dissipation as compared to the previous structures.
