Abstract

A reversible logic based serial to parallel converter is developed using Quantum cellular automata (QCA). Nowadays reversible logic is a vital area of research due to its aptness to reduce the power dissipation and circuit complexity. The output functions uniquely expound by the input logical states in reversible logical functions. The foremost aim of designing the reversible circuits are to reduce the number of gates, number of garbage outputs, delay, quantum cost, number of quantum cells and device complexity. The reversible logic circuits do not fail to keep the information and unique types of outputs are taken. In this paper a proposed new 4*4 reversible gate is designed using quantum cellular automata and it is being used to realize the D Flip Flop with reduced number of quantum cells. Also a 4 bit reversible SIPO serial to parallel converter has been realized using the proposed D Flip Flop. It uses reduced number of gates and quantum cells so it occupies less area.
