Experimental and Simulation Results of Wien Bridge Oscillator Circuit Realized With Op-Amp Designed Using a Memristor

Abstract

In this study, a new op-amp model was created by re-designing the internal structure of the traditional operational amplifier (741 family) circuit element with a linear dopant drift TiO2 memristor (LDDTM) emulator model. The optimized working conditions and states of this proposed op-amp model were determined. Wien bridge oscillator circuit realized with memristive based op-amp model has been investigated on oscillating start time, settling time, fast fourier transform (FFT) analysis and output parameters. In addition, the efficiency of the wien bridge oscillator circuit realized with a memristor-based opamp has been tested with application circuits and the accuracy and applicability of the proposed memristor-based opamp model has been extensively examined theoretically and supported by experimental and simulation results. Finally, both the simulation and experimental results of the oscillator circuits realized with a memristor-based opamp are presented in detail in tables.
