A pipelined analog-to-digital converter (ADC) comprises a first stage that receives an input voltage signal and that comprises an analog-to-digital converter (ADC). The ADC includes an amplifier having an input and an output. N capacitances are connected in parallel and include first ends that selectively communicate with the input and second ends. N switches selectively connect the second ends of the N capacitances to the voltage input during a first phase, one of the second ends of the N capacitances to the output of the amplifier during a second phase, and others of the second ends of the N capacitances to one of a voltage reference and a reference potential during the second phase. A second stage communicates with the output the amplifier.
