Abstract

The invention relates to an electronic circuit comprising a first comparator having a first input offset voltage, wherein the first comparator is operatively coupled to a first sampling capacitor, a second comparator having a second input offset voltage, wherein the second comparator is operatively coupled to a second sampling capacitor, and a control circuit operatively coupled to the first comparator and the second comparator for generating alternate cycles having a first phase and a second phase, wherein a first sampled offset voltage is stored in the first sampling capacitor during the first phase of the alternate cycles, wherein the first sampled offset voltage is subtracted from the first input offset voltage during the second phase of the alternate cycles, wherein a second sampled offset voltage is stored in the second sampling capacitor during the second phase of the alternate cycles, and wherein the second sampled offset voltage is subtracted from the second input offset voltage during the first phase of the alternate cycles.
