摘　　要：由于互补金属氧化物半导体（CMOS）器件尺寸的限制,量子元胞自动机（QCA）成为有望替代CMOS的新兴纳米器件。量子元胞自动机具有超低功耗、超高速度和高密度结构的潜在优势。提出了一种新型的同或门结构,在面积、延迟、复杂度及功耗方面相较于之前的结构均存在优势。所提出的新型同或门结构仅使用28个面积为0.02μm^2的QCA元胞,延迟仅为0.75个时钟周期。为了检验提出的设计在大型复杂QCA电路中的性能,实现了4,8和16位的奇偶校验器电路。模拟结果表明,所设计的电路性能各方面均优于先前的设计。Due to the size limitation of complementary metal-oxide-semiconductor（ CMOS） devices,a quantum cellular automata（ QCA） becomes a new nanometer device that is expected to replace CMOS devices. QCA has the potential advantages of ultra-low power consumption,ultra-high speed and high density structure. A novel XNOR structure with advantages compared to the previous structure was proposed,including area,delay,complexity and power consumption. The proposed XNOR structure used only 28 QCA cells with an area of 0. 02 μm^2. The delay of the structure was only 0. 75 clock cycles. In order to check the efficiency of the proposed design in the large and complex QCA circuit,the parity check device circuits with 4,8 and 16 bits lengths were implemented. The simulation results show that the performance of the designed circuit are better than that of the previous designs.
