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 , Ẋ ] plane and an [ f 1 ( X , Ẋ , Ẍ ), Ẋ ] plane. The latter is revealed numerically and experimentally where f 1 ( X , Ẋ , Ẍ ) is a simple algebraic sum of scaled X , Ẋ and Ẍ . A homoclinic orbit is included.
