Design of Memristor High-Pass Filter Circuit

Based on the Hewlett-Packard amnesia resistor, an equivalent circuit model is developed, and circuit analysis and simulation are performed. From the simulation results, it is concluded that the equivalent circuit model of the memristor has a memory function and has the basic characteristics of a memristor. The cutoff frequency of the filter circuit is obtained by replacing the resistor in a common filter circuit with an analog circuit of an amnesia resistor, and the AC small-signal scan of the transformed filter circuit is analyzed. After the simulation analysis of different input signals, it is concluded that the circuit design meets the requirements of high-pass filtering circuit and has good filtering effect.
