ABSTRACT:
A low power serial A/D converter cascades multiple stages (20) of a novel track-and-hold circuit (22) to implement a pipelined A/D converter. The track-and-hold circuit (22) is implemented using a differential structure to cancel out signal droop. This allows extremely high tracking bandwidths to be achieved while maintaining long hold times. Each stage (20) of the pipeline includes a binary quantizing circuit (24) which performs a 1-bit binary estimate of the data and a summing circuit (26) which updates the output of its track-and-hold circuit (22) to allow the next bits to be decided by the following stages.
