Abstract :
A novel concept is presented for the generation of truly random signals for analog/digital VLSI circuits. It is based on the analog implementation of very simple chaotic discrete-time systems. This concept is demonstrated via two monolithic Switched-Capacitor CMOS prototypes (respectively in a 2 μm double- metal single-poly technology and in a 3 μm double-metal double-poly one). Both analog and digital random signals have been measured from these prototypes to illustrate the validity of the proposed approach.
