An Improved SPICE Macromodel of Memristor for General Applications

This paper introduces an improved SPICE model of memristor using dependent sources and switches. The proposed SPICE model with two parameters in dependent current source has ideal frequency and amplitude characteristics. We simulate two circuits with memristor. The results demonstrate that the memristor can “remember” last resistance value when no current passes through it, the Amplitude Modulation (AM) circuit with memristor and op-amp is simulated under the condition of high frequency. Since the memristor has great performance in frequency there might be a possible application of the memristor to be used as modulator or demodulator in wireless communication.
