“…(2) The memristor is locally active and the locally-active region is symmetrical about the origin. (3) The memristor has a S-type DC V-I plot and a nonvolatile power-off plot, which is different to the nanoscale LAMs and the S-type LAM in Ref [30] with volatile resistance. The rest of this paper is organized as below: In Section 2, the mathematical model of S-type bistable locally-active memristor is presented and the voltage-current characteristics are analyzed by coexisting Pinched hysteresis loops, power-off plot and DC V-I plot.…”

“…Recently, a new type of nanoscale devices of locally-active memristor, called S-Type LAM, was proposed [27][28][29]. And a S-Type LAM model with volatile resistance was then proposed [30]. S-Type LAM is a nonlinear local active device, which is simpler in concept than the passive memristor with negative resistance, thus it can form an oscillation circuit without pure negative resistor.…”

“…Therefore, S-type LAM is preferred over other memristor in the design of chaotic oscillator [35][36][37]. In Ref [30], Wang designed a S-type LAM-based chaotic oscillator by using a resistor, a capacitor and an inductor. However, it is not clear whether S-type LAM could be used to other oscillating circuits such as Wien-bridge circuit.…”

In this paper, a S-type memristor with tangent nonlinearity is proposed. The introduced memristor can generate two kinds of stable pinched hysteresis loops with initial conditions from two flanks of the initial critical point. The power-off plot verifies that the memristor is nonvolatile, and the DC V-I plot shows that the memristor is locally active with the locally-active region symmetrical about the origin. The equivalent circuit of the memristor, derived by small-signal analysis method, is used to study the dynamics near the operating point in the locally-active region. Owing to the bistable and locally-active properties and S-type DC V-I curve, this memristor is called S-type BLAM for short. Then, a new Wien-bridge oscillator circuit is designed by substituting one of its resistances with S-type BLAM. It find that the circuit system can produce chaotic oscillation and complex dynamic behavior, which is further confirmed by analog circuit experiment.

“…Furthermore, diverse locally active characteristic curves indicate the complex polymorphic of locally active memristors. Liang et al [11] proposed an S-type locally active memristor, then constructed an equivalent analog circuit, and a small signal equivalent analog circuit that is used to reveal the influence on the amplification of extremely small fluctuation in energy in the locally active region. By introducing an inductor and a capacitor to the memritor circuit, a third-order chaotic oscillator was found and analyzed in [11].…”

In this paper, a new type of non-volatile locally active memristor with bi-stability is proposed by injecting appropriate voltage pulses to realize a switching mechanism between two stable states. It is found that the memristive parameters of the new memristor can affect the local activity, which has been rarely reported, and this phenomenon is explained based on mathematical analyses and numerical simulations. Then, a locally active memristive coupled neuron model is constructed using the proposed memristor as a connecting synapse. The parameter-associated dynamical behaviors are revealed by bifurcation plots, phase plane portraits and dynamical evolution maps. Moreover, the bi-stability phenomenon of the new coupled neuron model is disclosed by local attraction basins, and the periodic burster and multi-scroll chaotic burster are found if a multi-level pulse current is used to imitate a periodical external stimulus on the neurons. The Hamiltonian energy function is calculated and analyzed with or without external excitation. Finally, the neuronal circuit is designed and implemented, which can mimic electrical activity of the neurons and is useful for physical applications. The experimental results captured from the
