Abstract
A pipelined analog-to-digital (A/D) conversion system enhances the effective data rate of the converter in direct proportion to the number of stages in the pipeline. The pipelined A/D converter operates in conjunction with a charge-coupled device (CCD) multilevel storage (MLS) in a three-bit (eight-level) implementation. Three comparators are used in the three-bit system arranged in a sequential successive approximation configuration with control circuits and a CCD shift register.
