Abstract

A numerical study is carried out on the dynamics of a non-autonomous chaotic circuit. The parametrical dependencies and features of a time-dependent circuit are explored. A novel feature of the present circuit model is that it contains a new non-autonomous nonlinear sub-circuit, namely, a non-autonomous Chua's diode (NCD), which indicates nonlinear resistor behaviour and enhances the complexity of the standard Chua's diode. Periodic cases are observed as functions of voltage f, driving frequency omega and the frequency of NCD phi. Chaos occurs for appropriate system parameters.
