Abstract
Official abstract text for this publication.
An analog to digital converter comprising at least one sampling capacitor connected to a sample node, and a pre-charge circuit arranged to cause the voltage on the sample node to substantially match the input voltage prior to the analog to digital converter entering an acquire mode in which the sample node is connected to the input node by a sample switch.
First claim
Opening claim text (preview).
The invention claimed is: 1. An analog to digital converter comprising at least one sampling capacitor connectable to an input node, and a pre-charge circuit arranged to cause a voltage at a sample node of the at least one sampling capacitor to substantially match an input voltage of the input node prior to the analog to digital converter entering an acquire mode in which the at least one sampling capacitor is connected to the input node by a first sample switch, wherein the pre-ch…
