Abstract
An analog input signal is dithered using a dithering sequence and then partially chopped using a chopping sequence. The dithered and partially chopped signal is then digitized by analog-to-digital converter (ADC) slices operating in alternating fashion, and the resulting digitized signals are adjusted according to the dithering sequence and the chopping sequence to compensate for gain and voltage offset errors of the ADC slices.
