Kalman filtering applied to the calibration of a highresolution analog-to-digital converter

The paper proposes the application of the Kalman filter in dc calibrations of analog-todigital converters with a Zener or a Josephson dc voltage reference standard. Repeated measurements over the entire full-scale range of an analog-to-digital converter with posterior Kalman filtering allow optimal estimation of its deviations in respect to a dc reference to be obtained, yielding improved assessment of converter's linearity.
