ABSTRACT:
Pipelined converter systems include a plurality of converter stages in which some stages generate and pass a residue signal to a succeeding stage for further conversion. The generation of the residue signal can inject spurious charges into a reference source that is used in the generation. The spurious charges reduce the accuracy of the residue signal and the accuracy of the system. Residue generator embodiments are thereby formed to provide reduction charges to the reference source that are arranged to oppose and reduce the spurious charges. This reduction of spurious charges significantly enhances system accuracy and linearity.
