Single missing cell deposition defect analysis of sequential reversible circuit

Power and heat dissipation problems of current CMOS (Complementary Metal Oxide Semiconductor) technology can be overcome by the reversible logic. All the basic reversible gates are implemented using QCA (Quantum dot Cellular Automata) nanotechnology. In this paper reversible logic based sequential circuit, SR latch, is implemented. This paper presents the implementation of Fredkin reversible gate using basic primitives of QCA, Majority Voter (MV). As defects are more likely to occur in this nanotechnology. Hence single missing cell deposition defect in QCA in reversible SR latch are analyzed using QCADesigner tool at the layout level.
