Calibration circuit and calibration method for ADC
The invention discloses a calibration circuit and a calibration method for an analog-to-digital converter (ADC). The calibration method of the ADC includes the following steps: (a) resetting the voltage at the first input of the comparator and the voltage at the second input of the comparator; (b) changing a terminal voltage of at least one capacitor in the first capacitor group; (c) the ADC generating a first digital code; (d) after the first digital code is obtained, resetting the voltage at the first input of the comparator and the voltage at the second input of the comparator; (e) changing a terminal voltage of at least one capacitor in the third capacitor group; and (f) the ADC generating a second digital code. The first digital code and the second digital code are used to correct the output of the ADC.
