Abstract :
This paper proposes a mixed-signal map-configurable chaos generator suitable for silicon integration, and makes an exhaustive analysis of its error sources and tolerance to the onset of saturation. The developed methodology has been applied in the design, embedded in a complete frequency-modulated differential-chaos shift keying (FM-DCSK) modem, of a chaos generator which achieves 10 bit resolution at a maximum clock frequency of 20 MHz, from a 3.3-V power supply.
