Abstract

In this study, filter circuits which are frequently encountered in analog studies are studied, starting from the linear drift TiO2 memristor emulator circuit. Filter circuit features can be improved by adding different circuits to the output stage today. This method significantly affects the filter circuits as a load impedance at output stage. It is aimed to increase the success of the output responses by making an experimental study of both active and passive analog filter circuits with the memristor emulator circuit. The performance of an analog filter can generally be understood by looking at the quality factor, the Bode diagram and the wall effect on the cut-off frequencies. These output parameters are sufficient conditions for examining the output responses of all analog filter circuits. Then, low, medium and high frequency analyzes on active and passive analog filters were examined and quality factor, Bode diagram and cut-off frequencies were compared. As a result, when the overall responses of the system are considered one by one, it has been observed that at low frequencies, analog filters with active and passive low-pass memristor follow a more stable output response and a curve closer to the wall effect than conventional filters. It has been demonstrated both experimentally and numerically that analog filters with active and passive high-pass memristor at high frequencies provide partial improvement over conventional filters. Experimental study of memristor-based filter circuits will inspire curious researchers for filter studies that can be designed according to the desired purpose in future studies.
