چکیده مقاله :
Quantum-dot cellular automata (QCA) is a new and very attractive technology for implementing logic gates and digital circuits at the nanoscale. This technology has very attractive and amazing features such as: low area, high processing speed and low power consumption. Over time, with the advancement of science and technology, there is hope that QCA technology will replace today's VLSI technology. Minority gates are one of the most important elements in digital circuit design. In this paper, a smart four-input minority gate is presented and it is the first time that a priority four-input minority gate is proposed. The proposed minority gate architecture is evaluated and simulated using the QCADesigner tool version 2.0.3. The results show 100% accuracy. By using this type of gates, the hardware required to design QCA circuits can be significantly reduced.
