Abstract
A compensation circuit of realizing equivalent capacitance amplification is provided. The compensation circuit includes an error amplifier, a resistor and a capacitor. A first terminal of the resistor is connected to a first output terminal of the error amplifier. A second terminal of the resistor is connected to a second output terminal of the error amplifier and the capacitor. An amplified error current signal outputted from the first output terminal of the error amplifier flows through the resistor, and is then divided into a capacitor charging signal and an error amplified reverse current signal. The capacitor charging signal flows to the capacitor. The error amplified reverse current signal flows through the second output terminal of the error amplifier into the error amplifier. The error amplified reverse current signal is larger than the capacitor charging signal.
