Abstract
A pipelined analog to digital converter in which data samples ripple down through the pipeline of comparator stages. Each stage of the pipeline includes switch capacitor amplifiers for comparing an analog signal to a first reference voltage, to a second reference voltage, and to an average of the first and second reference voltages. Fan out of circuit components can be eliminated in succeeding stages, and error correction is provided by including overlapping of ranges passed by an earlier stage to a subsequent stage.
