Abstract
Various embodiments of the present technology may provide methods and apparatus for a successive approximation register analog-to-digital converter (SAR ADC). The SAR ADC may provide a first digital calibration circuit configured to correct systemic mismatch and a second digital calibration circuit configured to correct random mismatch. Together, the first and second digital calibration circuits resolve missing codes in the SAR ADC output.
