New tunable resistorless grounded meminductor emulator

In this research article, a grounded resistorless meminductor emulator is proposed. The proposed emulator uses one voltage differencing transconductance amplifier (VDTA) and one operational transconductance amplifier (OTA) with corresponding grounded capacitances. It can be operated in both decremental and incremental configurations. The comparison of the proposed emulator with available literature is also included. The proposed meminductor emulator circuit has been designed and simulated in Cadence Virtuoso Analog Design Environment using 180 nm gdpk technology parameters. Moreover, the application of the proposed emulator as a second-order bandpass filter (BPF) is also given. The simulation results agree well with the theory and confirm the meminductor functionality.
