Abstract:
The present disclosure relates to a method of self-calibration of a successive approximation register-analog-to-digital converter. The method includes measuring an error value for each thermometer element of a plurality of thermometer elements and determining a mean value of measured error values. The method also includes generating a thermometer scale where each level of the thermometer scale will be an incremental sum of each value of a first subset, and each further level of the thermometer scale will be a sum of all values of a second subset plus the incremental sum of the elements of the first subset in any order. In addition, the method includes generating the output code according to the thermometer scale.
