A digital calibration technique to linearize capacitor mismatch, residue amplifier gain, and nonlinearity in a two-step ADC based on the split-ADC technique [1] is presented. Although multiple publications have been reported before on the split-calibration of pipelined ADC's, none of them is comprehensive, meaning capacitor mismatch, residue gain, and… CONTINUE READING
