摘要:
设计一种基于混合二极管的Sallen-Key低通滤波振荡电路,将PN结型二极管与电感、电容串并联组合所构成的混合二极管接入低通滤波电路的输入端,构建一种具有复杂动力学行为的混沌振荡电路. 引入不对称系数来模拟实际电路中二极管元件之间电学特性的偏差,通过特定参数的相轨迹图、分岔图和Lyapunov指数谱对振荡电路的对称、不对称系数下两种振荡状态进行数值分析. 实验产生振荡电路中独特的吸引子共存现象,揭示了受电路参数调节的对称、不对称共存分岔、反单调特性等丰富的动力学行为演化过程. 最后,基于FPGA技术完成振荡电路的数字电路实验,验证了数值仿真的正确性和物理可实现性.
Abstract:
In this paper,a kind of Sallen-Key low-pass filter oscillator circuit based on hybrid diode is designed. The hybrid diode composed of PN junction diode,inductor and capacitor is connected to the input end of the low-pass filter circuit,and a chaotic oscillation circuit with complex dynamic behavior is constructed. Asymmetry coefficient is introduced to simulate the deviation of electrical characteristics between diode elements in the actual circuit. The phase trajectory diagram,bifurcation diagram and Lyapunov exponential spectrum of specific parameters are used to numerically analyze the two oscillation states under the symmetry and asymmetry coefficient of the oscillation circuit,and the unique attractor coexistence phenomenon in the oscillation circuit is found. The rich dynamic behavior evolution processes such as symmetric,asymmetric coexisting bifurcation and anti-monotone characteristics regulated by circuit parameters are revealed. Finally,based on FPGA technology,the digital circuit experiment of oscillation circuit is completed,and the correctness and physical realizability of numerical simulation are verified.
