摘要：
A stage of a pipeline analog-to-digital converter (ADC) is provided according to embodiments of the present invention. The stage of the present invention has double-amplifier architecture and uses level-shifting technique to generate a residue of the stage. The amplifiers of the stage are implemented in two different split paths, thereby to generate a relatively coarse amplification result and a relative fine amplification result. The relatively coarse amplification result is used to level-shift the output level of the amplifier. As a result, the stage of the present invention can have a correct residual by using amplifiers of moderate quality.
