ABSTRACT:
An analog to digital conversion circuit includes a first circuit (10) for receiving an analog signal (16) applied to an input (e.g.,26) of the first circuit via a connection to an analog source (e.g.,18) and generating a first residue (58) of the analog signal at an output (e.g.,32). The first circuit may be selectively configurable in a first mode for integrating the analog signal to generate an integrated analog signal and configurable in a second mode for disconnecting the first circuit from the analog source while folding the integrated analog signal to generate the first residue. The analog to digital conversion circuit also includes a second circuit (60) coupled to the output of the first circuit for resolving the first residue provided by the first circuit and for generating a further resolved second residue (98).
