Design and implementation of 4-bit arithmetic logic unit using Quantum Dot Cellular Automata
Manisha G. Waje, Pravin K. Dakhole · 2013
Quantum Dot Cellular Automata is one of the six emerging technologies which help us to overcome the limitations of CMOS technology. Design of 4-bit ALU for AND, OR, XOR, and ADD operations using QCA is discussed through this paper. This design of 4-bit ALU using QCA is simple in structure having significantly lesser elements as compared to CMOS design. It also gives better result in terms of speed, area and power. A QCADesigner tool is used for Simulation of different components of 4 bit ALU.
