    Abstract: Provided are a Time-Interleaved Successive Approximation Register Analog-to-Digital Converter, TISAR ADC, and a calibration method thereof. The calibration method for the TISAR ADC may include: sampling an analog signal input into the TISAR ADC to generate a reference digital signal (S130); according to the reference digital signal and output digital signals generated by analog-to-digital conversion sub-modules of the TISAR ADC, obtaining capacitor array calibration parameters and time delay calibration parameters of the analog-to-digital conversion sub-modules; adjusting capacitor arrays of the corresponding analog-to-digital conversion sub-modules according to the capacitor array calibration parameters, respectively; and adjusting time delays of the corresponding analog-to-digital conversion sub-modules according to the time delay calibration parameters, respectively.
