Research progress of time-interleaved analog-to-digital converters

Channel mismatch calibration techniques of time-interleaved analog-to-digital converters (TI-ADCs) are reviewed. The research on sampling technology of TI-ADCs is introduced, and the influence mechanism of channel mismatch has been analyzed briefly. Subsequently, the latest research progress of the domestic and foreign error calibration techniques of TI-ADCs is elaborated. The implementation methods, advantages and disadvantages of each calibration technique have been summarized, existing problems are analyzed. Finally, future development trends are prospected. These works could provide a reference for advancing the research field.
