A variable gain amplifier application featuring a physical memristor available from Knowm Inc. is considered. A hardware prototype of the amplifier is built and variable gain programming response verified. An in situ current-voltage characterization of the device is performed, and a SPICE circuit model for the memristor is extracted and implemented for LTSpice simulations. Simulation results show good agreement with measured variable gain amplifier responses of the experimental hardware. The proposed memristor characterization method and SPICE modeling technique provide a useful approach for further simulation evaluation of application specific analog memristor circuits such as a variable gain amplifier.
