Abstract

An output stage circuit of an operational amplifier, the operational amplifier, and a signal amplifying method applied to the operational amplifier are provided. The output stage circuit includes an inverting circuit and a compensation module. The inverting circuit is electrically connected to a gain stage circuit of the operational amplifier. The inverting circuit generates an output signal of the operational amplifier. The compensation module includes a first compensation circuit, including a first current providing path and a first suppression activation circuit. The first current providing path provides a first compensation current. The first suppression activation circuit conducts the first compensation current to the inverting circuit if a first compensation condition related to a first gain stage signal generated by the gain stage circuit is satisfied. Variation of the output signal is suppressed because of the first compensation current.
