Abstract :
This paper presents a 2.4 /spl mu/m CMOS IC prototype which includes a programmable chaotic generator and some interface circuitry for chaotic encryption. It realizes a member of the family of the canonical Chua´s state equation. It exhibits several bifurcation parameters by changing a few external bias currents and can be used for the chaotic encryption of audio signals.
