Coexisting Multi-Dynamics Of A Physical Sbt Memristor-Based Chaotic Circuit

This paper presents a new physical Sr0.95Ba0.05TiO3 (SBT) memristor-based chaotic circuit. The equilibrium point and the stability of the chaotic circuit are analyzed theoretically. This circuit system exhibits multiple dynamics such as stable point, periodic cycle and chaos by means of Lyapunov exponents spectra, bifurcation diagrams, Poincare maps and phase portraits, when the initial state or the circuit parameter changes. Specially, the circuit system exhibits coexisting multi-dynamics. This study provides insightful guidance for the design arid analysis of physical memristor-based circuits.
