Design of Efficient and Testable n-Input Logic Gates in Quantum-Dot Cellular Automata



Quantum Dot Cellular Automata (QCA) is an emerging nanotechnology that can be considered as a possible alternative for replacing the conventional silicon MOSFET technology, in the near future. This paper presents a novel method for designing logic circuits with high efficiency, controllability and testability for QCA technology. The proposed n-input AND and OR circuits are designed based on n-input majority gate, whereas based on the conventional method of QCA logic circuit design, at most [n/2]-input AND and OR gates can be implemented using n-input majority gates.
