Abstract
An analog to digital converter comprises a first stage for developing a set of most significant bits from an analog input signal and for producing analog residue signals (RA, RB) corresponding to respective differences between the analog input signal and threshold values directly above and below, respectively, the analog input signal, and a second stage (AMPA, AMPB, ADC) for developing a set of lesser significant bits from the analog residue signals (RA, RB). According to the invention, the analog residue signals (RA, RB) are reversed (CA, CB). An offset detection unit (COD, DOD) coupled to the second stage (AMPA, AMPB, ADC) retrieves offset data representative of offset errors, and an offset correction unit (AD, AD, OCA, OCB) corrects the offset errors on the basis of the offset data.
