Abstract:
1. A method for producing a model of a memristor device for facilitating integrated circuit modeling and simulation, comprising the steps of: inputting a periodic signal into a memristor, said periodic signal having a minimum voltage amplitude, a maximum voltage amplitude, and a frequency; measuring and recording said memristor's output current at a plurality of discrete time intervals over at least one period of said periodic signal; plotting said output current versus input voltage over said at least one time period of said periodic signal; plotting said output current versus time over said at least one time period of said periodic signal; determining a high resistance state R determining a low resistance state R determining, from said plotted output current versus said input voltage determining from said plot of output current versus time a value of a magnitude fitting parameter K determining from said plot of output current versus time a value of a curvature fitting parameter K determining from said plot of output current versus time a value of a magnitude fitting parameter K determining from said plot of output current versus time a value of a curvature fitting parameter K where R R R R V T T K K K K Δt is the minimum integral time step parameter between successive memristor resistance measurements.
