Bibhash Sen, Anirban Nag, Asmit De, Biplab Kumar Sikdar · 2013
This work targets the design of a multiplexer in multilayer QCA (Quantum-dot Cellular Automata) framework. The proposed multiplexer satisfies the requirement of high device density as well as computing power. The impact of different design constraints, such as layer spacing, radius of induced effect and the size of QCA cell on logic synthesis in multilayer environment are thoroughly investigated. High level synthesis of digital design using the proposed multiplexer is explored that establishes the significant improvement in digital design with the layered structure over that of conventional design approaches.
