طراحی انرژی ناکارآمدی کارآمد از دروازه اکثریت 3 ورودی با پیاده سازی و اثبات فیزیکی آن در خودروهای کوانتومی نقطه سلولی

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.
