Abstract
A pipelined Analog-to-Digital Converter (ADC) stage includes a main sampling path having a first filter in series with a first sample and hold circuit and a sub-ADC sampling path having a second filter in series with a second sample and hold circuit driving a sub-ADC connected to a sub-Digital-to-Analog Converter (DAC). The frequency response of the main sampling path is matched to a frequency response of the sub-ADC sampling path such that a residue signal of the pipelined ADC stage stays within range.
