Five-input majority gate, a new device for quantum-dot cellular automata
Journal Publication ResearchOnline@JCUAbstract
Quantum-dot Cellular Automata (QCA) is one of the most attractive technologies for computing at nano-scale. The principle logic element in QCA is majority gate. In this paper, a novel design for 5-input majority gate is presented. A 5-input majority gate study has been proposed; however this study has changed the scheme of basic QCA cells. The new proposed device reduces cell counts and area and uses conventional form of QCA cells. Accuracy of this design is proven by applying some simple physical substantiation and QCADesigner tool is used for verifying majority circuit layout and functionality. Furthermore, a QCA Full-Adder is constructed using the new proposed design. Simulation results demonstrate that the proposed design of majority gates and Full-Adder resulted in significant improvements in designing logical circuits.
