Abstract
A pipelined analog to digital converter for converting an analog signal to a sequence of digital words, each such word representing a value of the analog signal at a time in a succession of times. The converter includes a sequence of analog to digital converter stages, each such stage generating at least one bit for each such word. A first such stage in the sequence receives the analog signal, and each such stage subsequent to the first stage receives a residue signal from a previous stage in the sequence. Each such stage includes an analog to digital unit that senses a sample of the analog signal and provides one or more bits representing a value of the sample. In at least one of the stages the analog to digital unit comprises a &Sgr;-&Dgr; converter.
