摘要：近期文献中报道了在具有自适应反馈突触的神经元模型中,随着参数的变化,存在从两个共存吸引子到一个相连吸引子再到两个共存吸引子的混沌转化现象.本文对此模型进行了电路设计,同时对具有非单调激活函数功能的电路设计进行了细致的研究,并利用Electronic Workbench(EWB)软件对所设计的电路进行了仿真实验,研究了电路中的混沌现象,验证了所设计电路的动力学行为与通过数值模拟结果十分相似.
In a neuron model with adaptive feedback synapse,with the change of parameters,the existence of two coexisting chaotic attractors,switching from the coexisting chaotic attractors to a connected chaotic attractor,and then switching back to the two coexisting chaotic attractors in this model were recently reported.An electronic circuit design for this model is described in detail in this paper.The circuit design of the non-monotonous activation function unit is also considered in detail.The designed circuits are simulated using the Electronic Workbench（EWB） software.Simulation results demonstrate that the dynamical behaviors of the designed circuit are closely similar to those in numerical simulations.
