Abstract
A system and method of reducing the effects of nonidealities of ADCs in multipath converters is disclosed. The system and method employs a variety of measure and correction blocks to determine statistical properties of the output stream of the multipath converter and to apply corrections to the operation of the subconverters of the multipath converter based upon differences in the measured statistics and expected target values, either explicit or implicit, for those statistics. A variety of examples of possible measure and configuration blocks are disclosed, as is the cascading of the measure and correction blocks to correct multiple errors in the output of the multipath converter. Feedforward (purely digital) and feedback (analog and digital) solutions are both disclosed.
