Abstract
An analog to digital converter transposes the input signal into two differential signals, which are applied to respective inputs of a differential comparator. The output of the differential comparator is linked to the input of the analog-digital converter by a circuitry loop for restoring a DC component of each of the differential signals at the mid-voltage of the conversion range of the analog-digital converter.
