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.
