A new floating memristor based on CBTA with grounded capacitors

This paper presents a new floating memristor emulator (FME) consisting of only a single current backward transconductance amplifier (CBTA) as the active element and two grounded capacitors. The proposed FME-based on CBTA enjoys some advantages that include minimum active and passive elements without using an analog multiplier circuit and grounded passive elements which are attractive for the integrated circuit. In addition, excluding the DC power supply voltage, it does not use bias voltage and/or bias current. The designed memristor circuit provides incremental and decremental characteristics without changing circuit topology or using a switching mechanism and it is implemented with a minimum of circuit elements. All simulation results for the memristor emulator were obtained as expected when compared with fabricated memristors. © 2019 World Scientific Publishing Company.
