Chaotic circuit based on physical memristor

In this paper, we briefly discuss the main features of the memristor-based autonomous oscillator introduced and extensively characterized in [1]. The circuit is based on two feedback loops, a linear one and a non-linear one involving a self-directed channel memristor. In particular, we consider two different types of devices, one tungsten-based and one carbon-based, and show experimental results proving that chaos can be readily obtained in both cases, despite the device non-idealities.
