Abstract
A multistage amplifier for outputting a first output signal includes: an input stage circuit, a middle stage circuit and an output stage circuit. The input stage circuit includes at least one amplifying circuit, which receives the first output signal and a reference signal, thereby to generate a second output signal at an output terminal of the input stage circuit. The middle stage circuit is used to perform frequency compensation on the multistage amplifier. The output stage circuit is used to generate the first output signal at an output terminal of the output stage circuit according to the second output signal. The output stage circuit includes at least one current limiting circuit, where the current limiting circuit is controlled by the second output signal, thereby to adjusting a voltage level of the first output signal.
