PROJECT TITLE :

A Novel Design of Flip-Flop Circuits using Quantum Dot Cellular Automata (QCA) - 2018

ABSTRACT:

As the device dimension is shrinking daily the conventional transistor based CMOS technology encounters serious hindrances thanks to the physical barriers of the technology like ultra-thin gate oxides, short channel effects, leakage currents & excessive power dissipation at nano scale regimes. Quantum Dot Cellular Automata is an alternate difficult quantum phenomenon that has a fully totally different computational platform to style digital logic circuits using quantum dots confined within the potential well to effectively process and transfer data at nano level as a competitor of ancient CMOS primarily based technology. This paper has demonstrated the implementation of circuits like D, T and JK flip flops using a derived expression from SR flip-flop. The kink energy and energy dissipations has been calculated to see the robustness of the designed flip-flops. The simulation results have been verified using QCA Designer simulation tool.
