/ ALGORITHMIC ANALOG-TO-DIGITAL CONVERTER WITH REDUCED DIFFERENTIAL NON-LINEARITY AND METHOD

摘要

An analog / digital converter section used in the analog / digital converter comprising a converter stage for calculating a digital output and a residue. Reg and dew output is applied to the over range stage, a stage in the over range and calculates the same second residue output of the first residue output reduced by the size of the reference voltage. Over range (over-range) stage is capable of operating with a relatively large feedback factor, increase the operating speed, commutation Tate (commutated) may reduce the differential non-linear error by the feedback capacitor switching.
