BANDWIDTH MISMATCH ESTIMATION IN TIME-INTERLEAVED ANALOG-TO-DIGITAL CONVERTERS

摘要

With high speed, high resolution time-interleaved (TI) analog-to-digital converters (ADCs), bandwidth mismatches between the various ADC branches can pose a significant problem. Previously, though, no adequate solution has been found. Here, a method and apparatus are provided that can calculate and compensate for bandwidth mismatches in a TI ADC, enabling a high speed, high resolution TI ADC to be produced.
