ABSTRACT:
A parallel pipelined analog-to-digital converter for use with chips containing large arrays of detectors is described. In these A/D converters, the degree of parallelism decreases between earlier and later pipeline stages. That is, there are fewer instances of at least one of the later stages than there are instances of at least one of the earlier stages. Thus, the instances of the earlier stages are responsible for processing a fewer number of pixels than are instances of the later stages. Viewed another way, the parallel pipelined analog-to-digital converter architecture of this invention assumes a tree or branched arrangement in which the earlier stages correspond to leaves and the later stage condense to branches. In an extreme example, the later stages coalesce to a single route.
