TLDR
A robust, efficient and scalable (RES) clocking scheme for QCA circuit is proposed which can facilitate three directional information flow within a single clock zone and overcome the complex multilayer wire crossing with most promising coplanar crossover.Abstract:
Fast pace growth in the IC industry is facing the challenges of feature size reduction which in turn demands an alternative to current CMOS VLSI. Quantum-dot cellular automata are emerging as one o...read more
