Investigating synchronization phenomena in chaotic ring oscillators coupled through memristive devices

Abstract

This paper aims to present the synchronization phenomena that emerge through the interaction of chaotic oscillators forming a network, coupled utilizing the promising characteristics of novel nanoelectronic circuit elements, namely memristors. This architecture exploits the reprogrammability feature of memristors to offer the capability of controlling the coupling radius of the oscillatory network without the need to modify its structure. Memristive devices can be manufactured in crossbar architectures, allowing for dense, reprogrammable structures. Chaotic CMOS ring oscillators (CMOS ROs) have been chosen as they provide a low-size and low-power consumption alternative that is easy to implement in ICs. Chaotic oscillators can be integrated with other hardware components, such as memristors, to create hybrid neuromorphic systems that combine the advantages of these technologies for the introduction of versatile, reconfigurable architectures.
