Analog-to-digital converting device and related calibration method and calibration module

摘要

An analog-to-digital converting device includes a converting module for sampling an input voltage according to a plurality of sampling signals, to generate a comparing signal; a control module, for adjusting the plurality of sampling signal according to the comparing signal, to generate a first digital signal corresponding to the input voltage and a plurality of weights; and a calibration module, for adjusting the plurality of sampling signal according to the first digital signal to make the control module generate a second digital signal and for adjusting the plurality of weights according to the first digital signal and the second digital signal; wherein the second digital signal is different from the first digital signal and is corresponding to the plurality of weights.
