Energy estimation of QCA circuits: An investigation with multiplexers

Abstract Quantum-dot Cellular Automata (QCA) is a rival to complementary-metal-oxide-semiconductor (CMOS)-based technology and one of the most cutting-edge nano-scale technologies. The multiplexer fundamental component in fields nano communication computation. investigative item this article QCA multiplexer, handful best multiplexers were chosen as samples for current experiment. layouts designed QCADesigner-2.0.3 simulation engine environment, was reported after successfully experimenting on total eight samples. co-ordinate-based energy estimated using QCADesigner-E (QDE), non-adiabatic waste investigated QCAPro. According coordinates-based technique, overall energy-saving 5.90 meV, with an average loss per cycle 0.537 meV. Another approach, QCAPro-based, used estimate at three different levels tunneling constant temperature, yielding approximately 12 15 meV energy-efficient multiplexers..
