Abstract

Quantum-dot Cellular Automata is one of the promising next-gen fabrics for circuits. Coplanar wire crossings is one of the more elegant features of this new low power computing paradigm. However, these need two types of cells and are known to be neither easy to fabricate nor very robust. In this work, we propose coplanar wire crossing using a single type of QCA cells, by applying the concept of Time Division Multiplexing to design the crossing. This has massive implications in fabrication and fault tolerance of QCA circuits.
