A pipeline ADC includes a pipeline structure having a plurality of analog-to-digital converting units cascaded in series; and a correcting unit coupled to the pipeline structure for correcting an output value of the pipeline structure according to a set of calibration constants. One of the analog-to-digital converting units contains a capacitor switching circuit. During error measurement of the pipeline ADC, the capacitor switching circuit switches to change capacitance allocation of the analog-to-digital converting unit so as to obtain the set of calibration constants.
