A switched-capacitor broadband noise generator for CMOS VLSI

Description

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 3ftm CMOS double-metal double-poly monolithic prototype yielding a 4V peak-to- peak signal with a flat power density spectrum from DC to about half the clock frequency.
