Estimating the term…
Various systems and methods for capturing data are disclosed. For example, some embodiments of the present invention provide methods for performing a first analog to digital conversion using a delta-sigma based analog to digital converter, and performing a second analog to digital conversion using a SAR based analog to digital converter. The delta-sigma converter provides a first portion of a conversion result, and the SAR based analog to digital converter provides a second portion of the conversion result. The methods further include combining the first portion of the conversion result with the second portion of the conversion result to produce a combined conversion result.
(canceled)
An analog to digital converter, wherein the analog to digital converter includes a first stage and a second stage, wherein the first stage provides a first result and a residue, wherein the first stage operates as a delta-sigma based analog to digital converter, wherein the second stage receives the residue and provides a second result, wherein the second stage operates as a Successive Approximation Register based analog to digital converter, wherein the first stage includes an operational amplifier and a comparator, wherein an output of the operational amplifier is electrically coupled to an input of the comparator, and wherein the second stage reuses the same operational amplifier and comparator.
