Abstract
An alternative method for characterizing capacitor matching is presented. The basic idea of this method is to sense the mismatch among the capacitors by amplifying the error voltage using an iterative switched-capacitor scheme. Through simulation, this method has shown an attractive property for sensing capacitor mismatches down to 1% and smaller.
