| 摘 要： | 在分析研究整数阶忆容器模型和分数阶忆容器模型的基础上，提出了一种具有两个分数阶阶次的忆容器模型，并对其相关特性进行了分析。将此模型应用于有源低通滤波电路中，仿真分析了含有分数阶忆容器的有源低通滤波电路的时域和频域特性。实验结果表明，与整数阶忆容器模型相比，提出的分数阶忆容器模型可以通过改变分数阶阶次来调整低通滤波电路的截止频率，进而改变低通滤波电路的滤波效果。

| Abstract: | Based on the analysis of integer-order and fractional-order memcapacitor models, a memcapacitor model with two fractional-orders is proposed. The related characteristics were analyzed. At the same time, this model was applied to active low-pass filter circuit. The time domain and frequency domain characteristics of the filter circuit were simulated and analyzed. The experimental results show that, compared with integer-order memcapacitor models, the proposed fractional-order memcapacitor model can adjust the cut-off frequency of the low-pass filter circuit by changing the fractional-order, and then change the filtering effect of low-pass filter circuit. |
