摘　　要：量子元胞自动机(quantum cellular automata,QCA)以其小尺寸、低功耗、高速度等特点被认为是一种有望取代互补金属氧化物半导体(complementary metal-oxide-semiconductor,CMOS)的新兴技术,但是其电路设计中导线交叉一直是个难点问题,该问题不仅带来相当高的设计成本,还会增加电路的复杂性和噪声敏感性。文章通过使用一些全新的逻辑门,重新设计了13种三输入标准函数,新设计实现了无导线交叉的目标,并且与之前最好的设计相比,在总的元胞数量、电路面积和延迟等方面分别优化了18.4%、15.4%、21.2%。Quantum cellular automata(QCA)is considered as a new technology that is expected to replace complementary metal-oxide-semiconductor(CMOS)because of its small size,low power consumption and high speed.However,wire crossing has always been a difficult problem in its circuit design,which not only brings considerable design cost,but also increases the complexity and noise sensitivity of the circuit.In this paper,13 kinds of three-input standard functions are redesigned by using some new logic gates.These new designs achieve the goal of no wire crossing,and the total cell count,circuit area,and latency are optimized by 18.4%,15.4%,and 21.2%,respectively,compared with those of the best previous designs.
