Abstract

The inductance simulator and the nonlinear resistor, which are constructed by operational amplifiers and resistors, are applied to complete the analog circuit implementation of Chua’s circuit as well as improve the accuracy of circuit parameters. The state variable z, which represents the product of the linear resistance and the current of the inductor, should be observed even if it is not an actual measurable physical quantity. It is found that z can be obtained via scaling of the voltage of the resistor in the inductance simulator. The real chaotic curves generated from the analog Chua’s circuit are displayed on the oscilloscope clearly. It demonstrates that the realization of Chua’s circuit is correct.
