Current-tunable chaotic jerk circuit based on only one unity-gain amplifier

Abstract

A new current-tunable chaotic jerk circuit is proposed based on a single unity-gain amplifier. The circuit initially demonstrates a feasible use of a simple unity-gain amplifier for a chaotic jerk oscillator. Bifurcation is adjustable using a current source. Chaotic attractors are illustrated on an [X,X] plane and an [f1(X, X, X), X] plane. The latter is revealed numerically and experimentally where f1(X, X, X) is a simple algebraic sum of scaled X,X and X. A homoclinic orbit is included.
