Abstract
A time-interleaved ADC error parameter extraction and correction method relates to an error correction technique for an analog-to-digital converter (ADC). This application discloses a method for extracting and correcting error parameters in a time-interleaved ADC, which takes the time-interleaved ADC channel n as the basis or reference channel, and corrects other channels to match the channel n. The steps include: a. Converting a time domain signal output of each ADC channel into a frequency domain signal; b. Calculating one or more error parameters according to the frequency domain signal; c. Correcting the frequency domain signal in one or more different channels according to the error parameter(s); and d. Converting the corrected frequency domain signal into a (corresponding) corrected time domain signal.
