Abstract
A digital correction method for dynamic range expansion of multiple ADCs includes: obtaining gain and offset correction values of other channels relative to a standard channel CHbased on iterative computations through positive and negative amplitude auxiliary values and positive and negative base values, then performing gain-offset error correction on the other channels, and then calculating phase differences of the other channels relative to the standard channel CHand constructing fractional delay filters with a Farrow structure corresponding to the channels, correcting sampling data X, . . . , Xafter performing the gain-offset error correction. Digital correction of sampling data collected from multiple channels in a multi-ADC system is realized while ensuring that respective dynamic ranges of the sampling data with different gains output by the multiple channels are not lost.
