Abstract
A pipelined analog-to-digital converter (ADC) has a multistage structure, and the pipelined ADC includes a plurality of stages that form the multistage structure. Each of the stages includes a sample-and-hold (S/H) circuit, a flash ADC, and a digital-to-analog converter (DAC). The S/H circuit converts an analog input signal to a digital signal. The flash ADC detects a digital bit corresponding to the analog input signal. The DAC converts the digital signal to an analog signal, and amplifies a residue signal, which is a difference between the input analog signal and the converted analog signal, that is provided as an analog input signal of the next stage.
