Design and Implementation of 16-bit Arithmetic Logic Unit using Quantum dot Cellular Automata (QCA) Technique

摘要

Quantum Dot Cellular Automata (QCA) is an advanced nanotechnology that attempts to create general computational at the nano-scale by controlling the position of single electrons. Quantum dot cellular automata (QCA) defines a new device architecture that permits the innovative design of digital systems. QCA technology has large potential in terms of high space density and power dissipation with the development of the faster computer with smaller size & low power consumption.QCA help us to overcome the limitations of CMOS technology. In this paper, A design 16-bit arithmetic logic unit (ALU) based on the Quantum dot cellular automata (QCA) is presented. The simulation result of 16 bit ALU is verified using QCA Designer tool.
