CHARGE INJECTION PHENOMENA IN THE S²I CELL APPLIED TO SECOND ORDER SIGMA DELTA MODULATOR

S. Boujelben, D. Dallet, Ph. Marchegay

Abstract

In this paper we present a method for the modelisation of charge injection phenomena in sigma-delta modulators before implementation using switched current S²I techniques. Our study is focused on charge injection error modeling in MOS switches through a two steps sampling of memory cell modelled by MATLAB Software.
