✦ Synopsis

A family of chaotic oscillators with qualitative dynamics similar to the chaotic Colpitts oscillator is introduced. The oscillators use a single current feedback op amp, configured as a noninverting voltage-controlled voltage source, as the active building block, and a nonlinear element with an antisymmetrical current-voltage characteristic. A procedure for obtaining the chaotic oscillators by modifying simple harmonic oscillators is demonstrated. These chaos generators are suitable for high-frequency operation; device parasitics have negligible effect. Experimental results, PSpice circuit simulations and numerical simulations of the derived mathematical models are included.

Irregular evolution is observed in a chain of forced Duffing oscillators even when the maximum Lyapunov exponent is strictly negative. This phenomenon generalizes similar results previously obtained in the context of coupled-map lattices. The relationship with chaotic cellular automata is investigat
