Numerical Simulation of the Chua's Oscillator Based on a MOSFET Structure with a Cubic Nonlinearity

The article presents the results of numerical modeling of Chua oscillator based on a metal-oxide-semiconductor field-effect transistors (MOSFET) structure with a cubic non-linearity. An overview of the Chua's oscillator circuitry basis on MOSFET structures. The approximation equation of static current-voltage characteristic with a cubic non-linearity is presented, as well as oscillator mathematical model. The phase portraits of the Chua oscillator with cubic non-linearity, time diagrams and amplitude-frequency spectra of generated oscillations are obtained. The graphs of Lyapunov exponents are presented, depending on the coefficients change in the mathematical model of the Chua oscillator with cubic non-linearity, as well as the Poincaré map.
