This page describes a self-oscillating (or autonomous) chaos circuit described by a third order differential equation. In mechanics, the third derivative of a coordinate is called its „jerk“, as an extension of the terms „velocity“ and „acceleration“. The figure below gives the circuit diagram. The upper part of the figure details the structure of the building blocks or subcircuits used to build the main circuit. The main circuit, illustrated in the bottom part of the figure, consists of four subcircuits connected in a loop. The first three circuit blocks are voltage-controlled integrators (with „Z“ a capacitance) and the fourth is a voltage-controlled gain block (with „Z“ a resistance).
