Flip Flops Design in Quantum Dot Cellular Automata Technology: Towards Digitization

Quantum-Dot Cellular Automata (QCA) is a transistor-less technology. In QCA, Columbic repulsion between electrons in the quantum dots makes data transfer possible. This paper presents design of flip flops using proposed Rotated-Normal Cells with Displacement (RND) inverter and cell interaction method. The SR latch, Flip Flop (FF), D FF, T FF are developed QCA. gives total average energy dissipation 1.31e-002eV 1.19e-003eV respectively. It also delay 1 clock phase. Proposed provides 2.40e-002eV 2.18e-003eV respectively, depicting efficient dissipation. flop an area. FFs RND method can be best choice for future Nano communication to construct circuits less high speed.
