Study and circuit design of stochastic resonance system based on memristor chaos induction

Abstract Memristor chaotic research has become a hotspot in the academic world. However, there is little exploration combining memristor and stochastic resonance, and the correlation research between chaos and stochastic resonance is still in the preliminary stage. In this paper, we focus on the stochastic resonance induced by memristor chaos, which enhances the dynamics of chaotic systems through the introduction of memristor and induces memristor stochastic resonance under certain conditions. First, the memristor chaos model is constructed, and the memristor stochastic resonance model is constructed by adjusting the parameters of the memristor chaos model. Second, the combination of dynamic analysis and experimental verification is used to analyze the memristor stochastic resonance and to investigate the trend of the output signal of the system under different amplitudes of the input signal. Finally, the practicality and reliability of the constructed model are further verified through the design and testing of the analog circuit, which provides strong support for the practical application of the memristor chaos-induced stochastic resonance model.
