Özet

Mixed-mode chaotic circuit (MMCC) designed by combining the common dynamics of autonomous Chua's circuit and nonautonomous MLC (Murali-Lakshmanan-Chua) circuit is not only extremely simple system but also exhibits both autonomous and nonautonomous chaotic dynamics via a switching method. In this study, focusing on the alternative design of MMCC circuit, we have proposed Wien bridge-based MMCC circuit replacing the LC resonator of MMCC circuit with a Wien bridge-based RC configuration. Wien bridge-based MMCC circuit presents a harmony of both linear and nonlinear oscillations and it provides the possibility of studying linear oscillations, autonomous and nonautonomous chaotic oscillations in the same circuit structure. By using the Wien bridge RC configuration, MMCC circuit has more tuning circuit parameters and inductor element count is reduced. The circuit behavior of Wien bridge-based MMCC is confirmed by PSpice simulations.
