Modeling and analysis of substrate coupled noise in pipelined data converters

Abstract

This paper presents methods to model and analyze substrate coupled noise in pipelined data converters. The substrate noise models covers substrate types, such as lightly and highly doped substrates, and the analyzes includes the effects on the pipelined data converter performance from a variety of noise shielding techniques, such as guarding and wells. Classical approaches to prevent noise are investigated. It is found that in some cases these traditional design rules are no longer suitable and have to be redefined.
