Abstract
In accordance with an embodiment, a method for operating a successive approximation ADC comprising a first capacitor array includes measuring a first weight of an MSB-abit of the ADC by applying a first reference voltage to first terminals of capacitors of the first capacitor array corresponding to the MSB-abit, applying a second reference voltage to first terminals of capacitors of the first capacitor array corresponding to significant bits lower than the MSB-abit, applying the first reference voltage to first terminals of a first set of capacitors of the first capacitor array corresponding to significant bits higher than the MSB-abit, and applying the second reference voltage to first terminals of a second set of capacitors of the first capacitor array corresponding to the significant bits higher than the MSB-abit; subsequently, a weight of a capacitance of the capacitors corresponding to the MSB-abit is successively approximated.
