Abstract
A user transparent self-calibration technique for an analog to digital converter is described. The technique can correct for capacitor mismatch error with minimal additional power consumption. This is done by generating a calibration signal, one for each capacitor whose calibration is desired. The signal is interleaved with the input signal, and digitized by alternating with the input signal digitization using capacitor arrays.
