| 中文摘要: |
| 量子点元胞自动机(quantum dot-cellular automata, QCA)因其延迟时间短、功耗低以及占用面积小等优点被当作代替
CMOS 的新型技术之一。 针对 CMOS 器件尺寸日益减小导致的高功耗和电容寄生及串扰问题,本文首次利用 QCA 技术构建了
一种递归盒式滤波器。 其中,提出了一种全新的 QCA 全加器,较已提出的 QCA 全加器减少了 55%的电路面积;少使用了
56. 7%的元胞数;量子成本也降低了 10%以上。 并以此为基础设计了一种高效的行波进位加法器( ripple carry adder, RCA)以
及一种高效的进位选择加法器(carry select adder, CSA)来构成盒式滤波器的加法单元。 以此构建的盒式滤波器较一般 QCA 盒
式滤波器节省了 32. 6%的硬件资源;减少 20%的电路运行时间;减少了 48. 7%的功耗。 并使用 QCA Designer 仿真,结果表明,
本设计完全可以代替实现传统的盒式滤波器功能,并在效率、功耗、电路面积、资源占用方面均有显著降低。 |

| QCA is regarded as one of the new technologies to replace CMOS due to its advantages of short delay time, low power
consumption, and small footprint. In response to the high power consumption, capacitance parasitic, and crosstalk issues caused by the
decreasing size of CMOS devices, this paper constructs a recursive box filter using QCA technology for the first time. Among them, a
new QCA full adder has been proposed, which reduces the circuit area by 55% compared to the proposed QCA full adder. 56. 7% fewer
cells were used. Quantum costs have also been reduced by more than 10%. Based on this, an efficient RCA and an efficient CSA were
designed to form the addition unit of the box filter. The box filter constructed based on this saves 32. 6% of hardware resources compared
to general QCA box filters. Reduce circuit running time by 20%. Reduced power consumption by 48. 7%. And simulated using QCA
Designer, the results show that this design can completely replace the traditional box filter function, and significantly reduce efficiency,
power consumption, circuit area, and resource occupation. |
