Abstract:
A calibration device for calibrating an ADC comprising: an error estimator for estimating an error of a digital signal outputted from the ADC, the error estimator includes: a digital filter for filtering the digital signal to generate a filtered signal; and a least-mean-square module for performing a least-mean-square operation according to the filtered signal to generate an estimated error; and an error correction module for correcting the digital signal according to the estimated error.
