摘要/Abstract

摘要： 基于有源器件设计了一种新的悬浮型二端口忆容器的等效模拟电路。分别采用方波和正弦波作为激励信号,验证了忆容器等效电路的磁滞环和频率依赖特征。考虑到忆容器元件容抗的可控性,将其应用在滤波器电路中,能够获得可调的截止频率。借助PSPICE软件,分别基于电路模型和宏模型搭建了两种由忆容器元件组成的π型低通滤波电路。分析了滤波电路的输入输出关系,以包含高、低两种频率成分的电压信号验证系统的滤波能力,并与实验结果进行误差对比分析。结果表明此新型滤波电路可有效滤除高频信号,低通滤波能力良好,且在无控制条件下输出特性异于传统滤波电路,具有进一步研究和开发的价值。

Abstract: A new equivalent circuit for emulating floating memcapacitor based on active analog chips was designed. By taking square and sinusoidal voltage waveforms as excitation signals, respectively, the frequency-dependence of pinched hysteresis loops of the memcapacitor emulator was tested. In consideration of the controllable memcapacitance, memcapacitor was utilized to structure filers in order to obtain tunable cutoff frequency. Based on PSPICE software, circuit and macro models were used to construct π filter circuits, respectively. Voltage signal containing low and high frequency components were used to test the low pass filtering ability of this circuit. The behaviors of filtered output and simulation errors were analyzed. The testing results indicate that these new filters have different input-output characteristics from typical filters consisted of traditional circuit elements and can be widely used in future circuit design.

Key words: memcapacitor, PSPICE, filter circuit, cutoff frequency
