Abstract
Disclosed are new methods and systems for achieving calibration in a pipelined ADC system. The methods and systems may be used to provide continuous digital background calibration in a pipelined ADC. Component mismatch error from each DAC in the pipeline is tabulated to provide an integral nonlinearity profile, which is subtracted from the ADC transfer characteristic.
