Combinational Circuit Design Based on Quantum-Dot Cellular Automata
Kondwani Makanda, Jun‐Cheol Jeon · International Journal of Control and Automation · 2015
Quantum-dot cellular automata(QCA) provides a new approach in computer circuit design and development at nanotechnology level.This technology promises extraordinary high computing speeds, low heat dissipation and highly dense circuits.In this paper,two 2:4 decodersare proposed.The proposed structures reduce the clock phases to only three phases making them faster than the designs currently available in literature.The first proposed structure has reduced number of cells and hence covers a small area.The second proposed method although it has more cells, has regular clock zones that can facilitate the implementation of this circuit.Simulation of the circuits was done using QCADesigner.
