Abstract

A compact chaos generator core circuit has been designed, fabricated, and tested. It generates PWM and PPM (pulse width and phase modulation) signals that follow arbitrary nonlinear analog dynamics. The measurement results show that PWM/PPM chaotic signals are generated at 1 MHz with a calculation precision of 6.7 bits at a supply voltage of 3.3 V. The circuit can be used for large-scale integrated noise sources or high-performance advanced neural networks using nonlinear analog dynamics.
