ABSTRACT:
A pipeline ADC has a plurality of analog-to-digital conversion units cascaded in series to form a pipeline. An error correcting method for the pipeline ADC includes during a first mode, measuring the plurality of analog-to-digital conversion units utilizing an extra analog-to-digital conversion module; calculating a plurality of correction constant sets according to digital output values of the extra analog-to-digital conversion module in the measuring step; and during a second mode, correcting output signals of the plurality of analog-to-digital conversion units according to the correction constant sets.
