An automatic gain control (AGC) topology with a variable gain amplifier utilizing a titanium dioxide (TiO2) memristor is described. A system analysis technique is developed based on the published physical charge-controlled memristor models and unique properties of this passive device. A linearized feedback loop amplitude model is used to design the AGC, and a design tradeoff analysis based on distortion performance is developed. The analysis results are verified with SPICE simulation including a TiO2 memristor SPICE model.
