Method and device for controlling a successive approximation register analog to digital converter

摘要

A method for controlling a successive approximation register analog to digital converter comprising connecting a first side of a capacitor to a first comparator input, during a sampling phase connecting the first side of a capacitor to an input and connecting a second side of the capacitor to a mid-voltage, following the sampling phase disconnecting the first side of the capacitor from the input and disconnecting the second side of the capacitor from the mid-voltage and autozeroing the comparator.
