Low-voltage, low-power, chaotic oscillator, derived from a relaxation oscillator

Abstract

A simple relaxation oscillator is designed by directly coupling a RC timing network to a passive S-shaped current-controlled nonlinear resistor and is then modified for chaos. The resulting chaotic oscillator inherits the main features of the relaxation oscillator, which are its low-power consumption and low-voltage operation from single or dual power supplies. These features are attributed to a simple two-bipolar-transistor passive nonlinear resistor. PSpice circuit simulations, experimental results and simulations of the derived mathematical models are included.
