  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.
