ABSTRACT:
A pipelined analog to digital converter comprises a first stage that receives an input voltage, that generates a first sampled digital value and a first residue voltage, and that includes a first amplifier that amplifies the first residue voltage and generates a first amplified residue voltage. A second stage receives the first amplified residue voltage, generates a second sampled digital value and a second residue voltage, and includes a second amplifier that amplifies the second residue voltage. At least one of the first amplifier and the second amplifier comprises a first transistor having a control terminal, a first terminal, and a second terminal, a transimpedance amplifier having an input that communicates with the first terminal of the first transistor, and an output, and an output amplifier having an input that communicates with the output of the transimpedance amplifier, and an output.
