Jerk Model Current-mode Chaotic Oscillator based on OTA
Main Article Content
Abstract
This paper describes a chaotic oscillator circuit based on Jerk model and nonlinear function. The signum function is
deployed to realize the chaotic oscillator which controlled by using a single parameter. The OTA and grounded capacitors are used without the resistors for achieving the chaotic oscillator. The circuit consists of main three parts, lossless integrator, biquadratic low-pass filter, and nonlinear function circuits. The condition of chaos signal can be electronically tuned through the quality factor of biquadratic low-pass filter. The simulation results are incorporated by PSpice and MATLAB which found that the chaos signal can be generated agree well to the theory. The chaos behavior can also be proved by bifurcation diagram. The signal output has doubling periods according to the circuit
results.
