Abstract
A method corrects the error in an output digital signal (Out) of an analog/digital converter (ADC) (), in which the error is introduced by a multibit digital/analog converter (DAC) () incorporated in the ADC. The method calculates () coefficients (p,pr) of a linear combination of vectors of a vector space representative of the error introduced by the DAC; calculates (--) the correlation of a signal (Res) containing the error introduced by the DAC, to extract an estimation of each vector; calculates a linear combination representative of the estimation of the error introduced by the DAC, and uses the estimation of the error introduced by the DAC to correct the ADC output signal.
