CMOS realization of OTA based tunable grounded meminductor

A simple and robust design for CMOS realization of a tunable grounded meminductor using three operational transconductance amplifier (OTA) and two capacitors have been proposed. Both theoretical analyses and simulation using Cadence Virtuoso at 0.18  $$\upmu {m}$$ CMOS technology parameters verify the validity of the meminductor. Its meminductance can be tuned with the help of external bias voltage and has an operating frequency of 10 MHz, which makes it suitable for high-frequency applications. The proposed meminductor can also be configured using both incremental and decremental mode by interchanging the pin of OTA. Various parameters variability analysis like process variation, capacitor variation, voltage variation, temperature variation, and frequency variation has been carried out and our proposed meminductor has shown excellent performance.
