Abstract

Quantum-dot Cellular Automata (QCA) is an attractive nanoelectronics paradigm which is widely advocated as a possible replacement of conventional CMOS technology. Designing memory cells is a very interesting field of research in QCA domain. In this paper, we are going to propose novel nanotechnology-compatible designs based on the majority gate structures. In the first step, this objective is accomplished by QCA implementation of two well-organized JK flip-flop designs and in the second step; synchronous counters with different sizes are presented as an application. To evaluate functional correctness of the proposed designs and compare with state-of-the-art, QCADesigner tool is employed.
