Abstract
In this paper, an extremely simple method to chaotify Wien-bridge harmonic oscillators is proposed. To make such circuit chaotic, only an additional hysteresis comparator is needed, which just contains one common opamp and three resistors. With this proposed scheme, the double-scroll attractor can be easily generated. The consequent circuit is investigated both numerically and experimentally. At last we give a rigorous verification of the existence of chaos in the attractor by virtue of horseshoe theory
