Abstract

The article explores the application of a reverse memristor emulator utilizing easily accessible components. This emulator comprises two Operational Amplifiers (Op-amps), one Operational Transconductance Amplifier (OTA), and two passive elements. The utilization of Op-Amps and OTA renders the circuit effortlessly implementable with commercially accessible Integrated Circuits (ICs), presenting a notable advantage of the suggested architecture. Upon close examination of the proposed design, accounting for terminal parasitics and non-ideal gains, the observed behavior closely matches the ideal characteristics of the circuit. The emulator’s functionality underwent testing in the PSPICE simulation environment, considering the 0.18 μm technology. The credibility of the proposed circuit concept was further substantiated by employing widely available ICs like µA741 and LM13700, with the results extensively discussed. Furthermore, the article showcases an essential application of this emulator by enhancing the bandwidth of a low-frequency memristor emulator. At last, the experimental results are also demonstrated to validate the reported application.

基于现成元件的逆忆阻器仿真器及其在忆阻器带宽扩展中的应用

本文探讨了反向忆阻器仿真器的应用，该仿真器利用易于获取的元件。该仿真器由两个运算放大器（Op-amps），一个运算跨导放大器（OTA）和两个无源元件组成。运算放大器和OTA的使用使得电路可以毫不费力地与商业上可访问的集成电路（ic）实现，呈现出所建议架构的显着优势。在仔细检查提出的设计后，考虑到终端寄生和非理想增益，观察到的行为与电路的理想特性非常匹配。考虑到0.18 μm技术，仿真器的功能在PSPICE仿真环境中进行了测试。通过采用μ A741和LM13700等广泛使用的ic，进一步证实了所提出电路概念的可信度，并对结果进行了广泛的讨论。此外，本文还通过增强低频忆阻器仿真器的带宽，展示了该仿真器的基本应用。最后，对实验结果进行了验证。
