CHAOTIC BEHAVIOR OF VOLTAGE CONTROL OSCILLATOR BASED ON COLPITTS OSCILLATOR
Abstract
In this paper, first a voltage-controloscillator based on colpitts oscillator has been considered to generate chaotic oscillation. Sensitivity to initial conditions is studied by considering a non-linearmodel of the system. Since, the main aim of this paper is to analyze a chaotic voltage control oscillator’s stability and the chaos behavior under the theoretical and the numerical methods, respectively. Then using Advance Design System (ADS)software, implementation of chaotic voltage-control oscillator based on colpittsoscillator is considered. . Thena methodology based on the energy distribution is presented using the DiscreteWavelet Transform (DWT)for chaos analysis. Simulation results are provided toshow the main points of the paper.
