A Novel Window Function for Memristor Model With Application in Programming Analog Circuits

A mathematical model for the TiO2 thin-film memristive devices found by Hewlett Packard Labs is proposed in this brief. By taking the current passing through the device into consideration and introducing two adjustable parameters, a novel window function is presented such that the resolution of the boundary lock, full scalability, and nonlinear ionic effects are simultaneously achieved. A comparison with some existing window functions is given. Finally, a programming analog circuit is designed to verify the applications and effectiveness of the memristive device equipped with the proposed window function.
