Abstract
A pipelined Analog-to-Digital Converter (ADC) includes circuitry to characterize capacitors associated with a Multiplying-Digital-to-Analog Converter (MDAC) of a stage of said pipelined ADC, said capacitors contributing to a gain of said pipelined ADC, circuitry to connect a subset of said capacitors not currently being characterized to reference signals of said pipelined ADC such that a residue signal of said stage stays within an input range of an instrument measuring said residue signal, circuitry to calculate said gain of said pipelined ADC using said capacitor characterizations, and an output adjusting component to digitally change an output of said pipelined ADC to compensate for said calculated gain.
