Simple optoelectronic chaotic generator: computer simulation and practical realization

Abstract

In this paper, the circuit of a non-autonomous generator that realizes chaotic behavior is presented. This oscillator-circuit contains four resistors, one capacitor, one inductor, two diodes, one operational amplifier, one bipolar voltage source and one sinusoidal source. All nominal of components are shown. The proposed circuit was modeled by utilizing NI’s MultiSim software environment. The system’s behavior was investigated through numerical simulations, by using wellknown tools of nonlinear theory, such as phase portrait, chaotic attractor and time distributions of two chaotic systemvariables. Spectral analysis are also presented.
