Abstract
A system includes a first tracking filter configured to track a frequency domain mismatch profile between component analog-to-digital convertors (ADCs) of an interleaved ADC (IADC), and a second tracking filter configured to a track a frequency independent timing delay mismatch and a timing delay mismatch correction error based on frequency domain mismatch profile estimates. An output of the first tracking filter determines a correction of a frequency dependent mismatch profile in an output of the interleaved ADC and an output of the second tracking filter determines a correction of the timing delay mismatch correction error in the output of the interleaved ADC.
