Abstract: An operational amplifier circuit including a main circuit, a compensation capacitor, a power circuit, and a set of switches is disclosed. The main circuit has an output terminal. The compensation capacitor has a first end connected to an internal node of the main circuit and a second end connected to the output terminal of the main circuit. The power circuit provides a current or a voltage as predetermined. The set of switches connects the power circuit to the compensation capacitor. When the main circuit is not in an output state, the set of switches is switched to allow the power circuit to provide the current or voltage to the compensation capacitor. When the main circuit is in the output state, the set of switches is switched to disconnect the power circuit from the compensation capacitor and allow the main circuit to return to an output circuit state and operate normally.
