Implementation of reversible logic design in nanoelectronics on basis of majority gates

Abstract

Due to low power dissipation in computing, reversible logic is an attractive field of research in quantum and optical computing. Since the conventional CMOS technology cannot be used for implementing reversible gates owing to its high power dissipation, employing novel technologies such as nano-scale ones are being deployed. In this paper we utilize Quantum-dot Cellular Automata (QCA) as a candidate technology for implementing reversible logic gates. This paper presents a new realization approach to reversible logic based on majority gates (MGs) and a new reversible gate is proposed as well. The gate will be compared with an existing MG-based structure in terms of delay, complexity and area. The results show that even though our gate requires more cells, it returns the outputs in less clock cycles and hence the design is faster.
