Abstract
Feedback compensation for multistage amplifiers. In some embodiments, an amplifier can include a first stage, a second stage, and a third stage implemented in series between an input node and an output node. The amplifier can further include a first feedback path implemented between an output of the third stage and a node between the first and second stages, with the first feedback including a first capacitance. The amplifier can further include a second feedback path implemented between the output of the third stage and an output of the second stage. The second feedback pack can include a transconductance element and a second capacitance arranged in series. In some embodiments, such an amplifier can be configured as an operational-amplifier.
