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.
