Design of a fault free Inverter Circuit using Minimum number of cells & related Kink Energy Calculation in Quantum dot Cellular Automata

Abstract: Quantum dot Cellular Automata (QCA) is the most promising nanotechnology in the field of microelectronics and VLSI systems. QCA-based circuits require less power with a high switching speed of operation compared to CMOS technology. QCA inverter is one of the basic building blocks of QCA circuit design. The conventional QCA inverter design requires many cells. In this paper, we design the QCA inverter circuit using a lesser number of cells. We showed the kink energy calculation for the QCA-implemented inverters as well as the polarization of the circuits.
