With being often studied in the field of nonlinear circuit theory, Chua's circuit and Chua's oscillator are the simplest autonomous kind of circuits which can become chaotic. There is only one nonlinear element in these circuits and it is very important to realize this nonlinear resistor that chaotic of these circuits can be illustrated. This paper presents three circuit realizations for the nonlinear resistor in the Chua's circuit and Chua's oscillator. At same time, we analyze the parameters of the element in one realizations for the nonlinear resistor in considerable detail.
