Abstract:Chua's circuit is a kind of chaotic circuit with simple structure and easy realization. Chua's diode is the core of Chua's circuit. Most of the existing Chua's diode models are implemented by dual-supply operational amplifiers and resistors. This paper sets the appropriate bias point for the operational amplifier and realizes the model of Chua's diode with a single power supply circuit. In the circuit implementation, the linear inductors used in the existing Chua’s circuit have the disadvantage of high price and difficult precision control. To tackle these problems, this paper takes the active simulated inductors to replace the linear inductors. The board-level circuit is designed and tested for two kinds of active simulated inductors. The test results indicate that using simulated inductor will not affect the chaos of the circuit under +5 V single power supply.
