Abstract :
A current-mode chaotic oscillator based on current amplifiers is studied. The oscillator operates on high frequencies and is suitable for on chip implementation. Its chaotic behavior is controlled by means of a bias voltage. Various methods for detecting chaos, such as the Lyapunov exponents, the Lyapunov dimension, the spectrum and the phase portraits are used, in order to confirm the chaotic behavior of the circuit. Simulation results, using a typical 0.35 mum CMOS technology, fully coincide with theoretical results.
