Experimental hysteresis in memristor based Duffing oscillator

This paper presents a practical implementation of a memristor based Duffing oscillator. We replace a diode based nonlinear element by a simple flux-controlled memristor in an existing circuit early proposed.We model the current-voltage characteristic and show experimentally that our circuit presents, for the same forcing amplitude, a route to chaos on the falling branch of the hysteresis loop, while its dynamics remains regular on the raising branch. This observation clearly highlights the memory effect of the memristor.
