In this study aimed to optimize the predictable region of the memristor hysteresis curve with the fuzzy logic designer tool by using the linear, doped drift TiO2 model as a memristor emulation circuit. Using this model, the current-voltage (I-V) curve of the memristor characteristic, that is, the hysteresis loop was created. In analog application studies, especially in filter circuits, being able to obtain a hysteresis loop in a certain frequency range leads to significant changes in the quality of the filter. At this point, various trial and error tests were performed for the most suitable parameter points. Here, the optimum hysteresis loop parameters were determined using a fuzzy logic designer. As a result, more practical and more stable results were obtained about the optimum hysteresis loop depending on the current-voltage and frequency information. In this way, users can get more predictable responses by determining the parameters according to the desired purpose and need. Especially in analog and digital electronic applications, they can approach the result more decisively by determining both the time loss and the workable area easily.
