Simulation results demonstrate that the proposed design of majority gates and Full-Adder resulted in significant improvements in designing logical circuits.Abstract:
Science and Research Branch of IAU, Tehran, IranQuantum-dot Cellular Automata (QCA) is one of the most attractive technologies for computing atnano-scale. The principle logic element in QCA is majority gate. In this paper, a novel design for5-input majority gate is presented. A 5-input majority gate study has been proposed; however thisstudy has changed the scheme of basic QCA cells. The new proposed device reduces cell countsand area and uses conventional form of QCA cells. Accuracy of this design is proven by applyingsome simple physical substantiation and QCADesigner tool is used for verifying majority circuitlayout and functionality. Furthermore, a QCA Full-Adder is constructed using the new proposeddesign. Simulation results demonstrate that the proposed design of majority gates and Full-Adderresulted in significant improvements in designing logical circuits.read more
