A memristor SPICE model for designing memristor circuits

The memristor, a circuit element, was first presented by Leon Chua in 1971. The physical implementation of the memristor was created by scientists at HP Labs in 2008 and the coupled variable resistor model was proposed. Here we show a SPICE model for such a memristor using dependent voltage sources. The model is validated by simulating simple circuits and comparing with the expected results. The proposed model makes it possible to design and simulate memristor circuits using SPICE. We simulate two circuits, a low pass filter in which a memristor is in series with a resistor and an integrator circuit with operational amplifier. The results are compared with inductor circuits in which a memristor is replaced by an inductor. The comparison shows that a memristor is acting like an inductor under certain conditions. Since the memristor has great performance in terms of power dissipation and with its nanometer size there might be a possible application of the memristor to be used as an inductor.
