Energy efficient neoteric design of a 3-input Majority Gate with its implementation and physical proof in Quantum dot Cellular Automata

Publication date: Available online 12 February 2018 Source:Nano Communication Networks Author(s): Sankit R. Kassa, R.K. Nagaria, R. Karthik Quantum dot Cellular Automata (QCA) is one of the most commendable approach besides the other alternative approaches, which has the proficiency to replace a well-known CMOS approach in near future. QCA technology possess small size, high speed of operation, high integration density capacity and ultra-low power consumption at nano-scale level. Various design paradigms of logic circuits related with QCA have been extensively studied in the recent past. A basic design of an Inverter and 3-input majority gate serves the purpose of the fundamental logic gates to design most of the QCA circuits with accuracy. In this presentation, a new design prototype of 3-input majority gate has been proposed, which is best suited to design QCA based circuits in variety of ways according to one’s own need. The proposed 3-input majority gate has the flexibility to change the position of its input as well as output QCA cells location from one place to another according to the need of a particular design. Physical proof and power dissipation analysis is derived for the proposed 3-input majority gate. Simulation results have been obtained by implementing various circuits based on the proposed 3-input majority gate and their output is verified using QCADesigner 2.0.3 tool.
