A Memristor-Less Meminductor Emulator Using DVCCTA and CDBA with Application in Adaptive Learning Circuit

A novel memristor-less meminductor emulator is proposed in this chapter which is realized using a differential voltage current conveyor transconductance amplifier (DVCCTA), a current differencing buffered amplifier (CDBA), a resistor, and two grounded capacitors. Several meminductor emulators that are reported in literature use memristor and their performances are often limited to either incremental or decremental configurations. In the proposed meminductor emulator, the provision of changing the responses of meminductor emulator from incremental to decremental and vice versa has been provided for both floating and grounded types. In addition, memristor has not been used in the design, which offers a compact design and the characteristics of meminductor emulator are not limited by the performance of memristor. It offers the advantage of extended frequency range. The pinched hysteresis loops have been obtained up to 5 MHz frequency for the proposed meminductor emulator’s incremental and decremental setups which are greater than many reported emulators. The simulation results were obtained with the help of the LTspice simulator using 180 nm CMOS technology parameters. We have also compared the performance of the proposed circuit with that of the existing meminductor emulators in the literature. To verify the effectiveness of the proposed meminductor emulator, an adaptive learning circuit has also been realized.
