摘要

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.
