Transient Noise Simulation Method for Memristor Circuits with Applications

Memristor noise simulation is addressed in this paper. Memristor has different noise generation mechanism from the CMOS devices, hence its simulation must be handled in SPICE-type simulators to support memristor-CMOS circuit design. We use the open source NGSPICE as the implementation code base and implement memristor noise simulation based on the existing noise simulation infrastructure. We verify that transient noise simulation can be conducted for circuits including both memristor and CMOS devices. By this enhanced simulation tool we are able to study experimentally the effect of memristor noise on the signal processing accuracy in memristive CMOS analog circuits such as a programmable linear equation solver.
