Abstract: A method for correcting an analog-to-digital converter includes the following steps: extracting gain errors and weight errors of all conversion stages of an analog-to-digital converter; performing first correction on the analog-to-digital converter based on the gain errors and the weight errors; extracting jitter errors of all conversion stages of the analog-to-digital converter after the first correction; and performing a second correction on the analog-to-digital converter based on the jitter errors. According to the disclosure, the gain errors, the weight errors, and the jitter errors of all conversion stages are successively extracted, and then the analog-to-digital converter is corrected. Precision after the corrections is higher.
