Electronically Charge-Controlled Tunable Meminductor Emulator Circuit With OTAs and Its Applications

Abstract

Studies on new passive elements with memory properties such as memristor, meminductor, and memcapacitor have increased recently. In this article, an operational transconductance amplifier (OTA) based meminductor simulator circuit without using a memristor, which is suitable for the physically produced memristor structure, has charge control, floating structure, and characteristics can be controlled electronically, is proposed. The OTA IC used is based on $0.18\mu \text{m}$ CMOS technology. The meminductor emulator circuit works in high-frequency regions and has low power consumption. Furthermore, the meminductor emulator circuit can be operated both as a decreasing model and an increasing model. Temperature, Monte-Carlo and worst-case analyzes are performed to verify the robustness of the proposed circuit. In this study, a chaotic circuit is designed by taking advantage of the nonlinearity of the proposed meminductor circuit. In addition, a neuromorphic circuit application has been carried out to demonstrate the memory ability of the proposed meminductor circuit. The electronic tunability of the proposed meminductor circuit in both chaotic and neuromorphic applications are demonstrated. The electronic simulations of the applications realized with the proposed meminductor emulator circuit, which are obtained by using the LTspice program.
