Title:
INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO2002091471
Kind Code:
A3
Abstract:
An integrated circuit (100) comprising an analogue circuit (30) and optionally a digital circuit (50) couples substrate noise present on the integrated circuit ground rail (114) onto a supply rail (116) of the analogue circuit. The voltage difference between the supply rail and ground is therefore substantially independent of the noise, thereby reducing or eliminating the impact of the noise on signals in the analogue circuit.
