摘要: Majority门作为多数逻辑电路的基本逻辑单元,其性能直接影响整体电路的质量.使用量子元胞自动机(QCA)设计Majority门具有结构简单的优点.本文提出了一种三层电路实现五输入Majority门的设计,并以此设计了全加器,进一步应用于多位加法器和乘法器中,与已发表的电路设计比较表明,其版图使用面积和元胞数有明显的减少,加法器元胞数和面积改进最高可达43%和87.2%,乘法器元胞数和面积改进最高可达48.2%和100%.

Abstract: Majority gate is core element of Majority logic circuit that affects the overall performance of circuit.The majority gate designed in Quantum-Dot Cellular Automata(QCA)has the advantage of simple structure.In this paper,a five-input majority gate with triple-layer design is proposed.Based on the designed five-input majority gate,full adder,adder and multiplier are designed.Compared with previous design,the simulation results show the number of QCA cells and area of the proposed adder are improved up to 43% and 87.2% respectively while those of the proposed multiplier are improved up to 48.2% and 100% respectively.

Key words: quantum-dot cellular automata, multilayer gate design, five-input majority gate, full adder, multiplier
