A study of chaotic circuits is of educational value, both to students and to practicing engineers. Ten circuits that behave chaotically are simulated with SPICE, starting with simple abstract systems and preceding, via familiar circuits such as the monostable and the tuned amplifier, to a controlled DC-DC power converter. The examples show a variety of ways in which chaos can arise in analog electronic circuits. It is shown how SPICE may be used to produce Poincare sections of strange attractors, and bifurcation diagrams.>
