基于模拟电感的蔡氏电路硬件实验

Hardware Experiment of Chua′s Circuit Based on Analog Inductance

蔡氏电路含有不易调节且成本高的电感元件,在教学实验中较难开展电路设计与硬件实验。对原始电感元件采用里奥登电感等效替换,通过Altium Designer软件绘制电路原理图,开展了基于模拟电感的蔡氏电路硬件实验。结果表明,基于模拟电感的蔡氏电路不仅能重塑经典蔡氏电路的动力学行为,其电感值还更易于调节,为大规模集成电路设计与创新性教学实验提供了优良方案。

Chua′s circuit contains the inductance which is not easy to adjust and expensive,thus it is difficult to carry out the circuit design and hardware experiment in teaching experiment.By replacing the original inductance with the Riorden inductance,the Chua′s circuit based on analog inductor is constructed thereby.The hardware experiments are carried out by drawing the circuit board in Altium Designer software.The results show that Chua′s circuit based on analog inductance can reconstruct the dynamics of the classical Chua′s circuit,and its inductance value is easier to adjust.Certainly,such circuit provides good schemes for developing the large-scale integrated design of Chua′s circuit and deploying the innovative circuit teaching experiment.
