Özet

© 2021 World Scientific Publishing Company.Memory circuit elements are of interest due to their use in different fields of science and technology. In this research, a new multi-outputs operational transconductance amplifiers (MO-OTA)-based memcapacitor emulator is proposed. The proposed emulator employs two OTAs, two capacitors, two resistors and an analog multiplier. The memcapacitor emulator circuit has electronically tunability property. Charge value of the memcapacitor can be adjusted by changing the transconductance gm value with the biasing current of the MO-OTA or frequency value of the input signal. In order to analyze the performance of the proposed circuit, memcapacitor emulator is simulated in 0.18μm TSMC CMOS process using LTSPICE and the simulation results are demonstrated.
