Abstract

A pipeline ADC is provided in which a DEM function and summation of sequences occur within a flash ADC. According to various aspects of the present disclosure, embedding the processing functions needed for DAC and amplifier error correction with the circuitry of a coarse ADC and rearranging the digital calibration blocks HDC and DNC ensures accurate estimation of the errors.
