Debajyoty Banik · 2016
In this article, sequential circuits have been designed which are based on reversible quantum dot cellular automata. Thus, the proposed designs have property of quantum dot cellular automata with essence of reversible logic. Gate count cannot be decent cost metric for optimization because each reversible logic gate is of computational complexity and distinctive type, so it will have a dissimilar delay and quantum cost. Computational complexity of reversible gate can be represented by its delay, quantum cost. Thus, primary objective of this article is design efficient latches in terms of garbage outputs, quantum cost, and delay. The various efficient r eversible latches including the positive level triggered D Latch, negative level triggered D Latch, T latch have been designs.
