OTA and CDTA-based new memristor-less meminductor emulators and their applications

This paper presents floating decremental and incremental meminductor emulators using operational transconductance amplifiers (OTAs), a current differencing transconductance amplifier (CDTA), and two grounded capacitors. The proposed designs are very simple in which a decremental meminductor emulator is converted into an incremental meminductor emulator by interchanging the input terminals of one of the OTAs. Pinched hysteresis loops have been obtained at different frequencies that verify the workability of the design. Non-volatility tests have also been performed to know the ability to remember the past history. All simulations have been done by the LTspice simulation tool of Analog Devices using 0.18 mu m technology parameters. The proposed meminductor emulators are utilized in the design of a chaotic oscillator and adaptive learning circuit. The simulation results obtained by the chaotic oscillator and adaptive learning circuit verify the efficacy of the proposed design.
