This paper proposed a digital circuit realization approach of Chua's circuit equation.By utilizing Euler's,the improved Euler's,and the Runge-Kutta algorithms,established the discrete iterative models of general chaotic system respectively,from which the discrete iterative models of Chua's circuit equation with different approximate precisions were deduced.Based on the chaotic system embedded digital integrated platform realized by microcontroller,the desired Chua's chaotic signals were generated and compared the performances of digital circuit realization of Chua's circuit equation realized by different algorithms.The results of numerical simulation and digital circuit experiments are in good agreement with those of Chua's chaotic circuit,which verify the feasibility of the proposed digital circuit realization methods.
