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

摘要

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 [,] plane and an [(,,), ] plane. The latter is revealed numerically and experimentally where (,,) is a simple algebraic sum of scaled , and . A homoclinic orbit is included.
