Abstract: The present invention provides a multi-stage amplifier, wherein the multi-stage amplifier includes a plurality of amplifier stages and a compensation circuit. The compensation circuit is coupled to an output terminal of one of the plurality of amplifier stages, and the compensation circuit includes a first auxiliary amplifier, a capacitor, a second auxiliary amplifier, a first resistor and a second resistor. The capacitor is coupled between an input terminal and an output terminal of the first auxiliary amplifier. The second auxiliary amplifier is coupled to the first auxiliary amplifier. The first resistor is coupled between an input terminal and an output terminal of the second auxiliary amplifier. The second resistor is coupled between an output terminal of the first auxiliary amplifier and a ground voltage.
