摘要：Quantum‐dot cellular automata (QCA) is an alternative complementary metal‐oxide‐semiconductor (CMOS) technology that is used to implement high‐speed logical circuits at the atomic or molecular scale. In this study, an optimal 2‐to‐4 decoder in QCA is presented. The proposed QCA decoder is designed using a new formulation based on the MV32 gate. Notably, the MV32 gate has three inputs and two outputs, which is equivalent two 3‐input majority gates, and operates based on cellular interactions. A multilayer design is suggested for the proposed decoder. Subsequently, a new and efficient 3‐to‐8 QCA decoder architecture is presented using the proposed 2‐to‐4 QCA decoder. The simulation results of the QCADesigner 2.0.3 software show that the proposed decoders perform well. Comparisons show that the proposed 2‐to‐4 QCA decoder is superior to the previously proposed ones in terms of cell count, occupied area, and delay.
