Abstract

A hierarchical parallel pipelined circuit includes a first stage with a plurality of sampling circuits and a plurality of corresponding analog or digital circuits that receive an output from the plurality of sampling circuits. A second stage includes a second plurality of sampling circuits and a plurality of corresponding analog or digital circuits that receive an output from the plurality of sampling circuits. A multi-frequency, multi-phase clock clocks the first and second stages, the multi-frequency, multi-phase clock providing a first clock having a first frequency having either a single or plurality of phases, and a second clock having a second frequency having a plurality of phases. A first phase of a plurality of phases is phase locked to the first phase of the first clock. The clock frequency multiplied by the number of parallel devices in each stage is the throughput of the circuit and is kept constant across the stages.
