An automatic gain control circuit with TiO 2 memristor variable gain amplifier

An automatic gain control (AGC) topology with a variable gain amplifier (VGA) utilizing a titanium dioxide (TiO 2 ) memristor is described. A system analysis technique is developed based on recently published physical memristor models and unique properties of the passive device. A linearized feedback loop amplitude model is used to design the AGC and the performance is verified with SPICE simulation including a TiO 2 memristor SPICE model.
