A semi-systematic procedure for producing chaos from sinusoidal oscillators using diode-inductor and FET-capacitor composites

A design procedure for producing chaos is proposed. The procedure aims to t ransfer design issues of analog autonomous chaotic oscillators from the non linear domain back to the much simpler linear domain by intentionally modif ying sinusoidal oscillator circuits in a semisystematic manner. Design rule s that simplify this procedure are developed and then two composite devices , namely, a diode-inductor composite and a FET-capacitor composite are sugg ested for carrying out the modification procedure. Applications to the clas sical Wien-bridge oscillator are demonstrated. Experimental results, PSpice simulations, and numerical simulations of the derived models are included.
