Low-Complexity MSB-Index LUT Digital Calibration for High-Resolution SAR ADCs

A digital calibration method with reduced LUT complexity is presented to suppress code-domain nonlinear errors caused by CDAC mismatch in high-resolution SAR ADCs. The method exploits the MSB-dominant and locally correlated behavior of mismatchinduced errors, so that interval-wise error estimation and correction can be...
