Unfolding the local activity of a memristor

This work models some dynamical properties of a volatile thermally-activated micro-scale memristor and the emergence of nonlinear oscillations when a capacitor is placed in parallel to it. A bias voltage input with a series resistor is used to drive the memristor into a locally-active state, from which, as theoretically envisioned by Chua, complex nonlinear behaviors may arise. Experimental measurements and modeling results based on Chua´s unfolding concept indicate that the local activity of the memristor is indeed at the basis for the occurrence of the limit-cycle oscillations.
