Abstract :
A switched-capacitor circuit is reported for the generation of broadband white noise in MOS VLSI. It is based on the implementation of a very simple chaotic discrete-time system. The concept is demonstrated via a 3 mu m CMOS double-metal double-poly monolithic prototype yielding a 4 V peak-to-peak signal with a flat power density spectrum from DC to about half the clock frequency.
