JK Flip-Flop Design Using Layered T Logic: A Quantum-Dot Cellular Automata-Based Approach

The Quantum-dot Cellular Automata (QCA) claims itself as a potential substitute for conventional transistors in multilevel digital circuit design. In this work, the Layered T Gate methodology is utilized in the JK flip flop design. The proposed QCA layout is compared with conventional designs in QCA metrics like effective area, delay, Costα. The QCA layout is generated, and simulation results are verified in a computer-aided design tool, namely QCA Designer 2.0.3.
