A feedback circuit is used for a power supply device. The power supply device includes a primary side circuit and a secondary side circuit. The feedback circuit includes a feedback voltage generation circuit, a base voltage generation circuit, and a compensation signal generation circuit. The feedback voltage generation circuit is electrically connected to the secondary side circuit. The feedback voltage generation circuit generates a feedback voltage according to a bias voltage and an output voltage of the power supply device. The base voltage generation circuit generates a base voltage according to the feedback voltage. The compensation signal generation circuit generates a compensation signal according to the feedback voltage and the base voltage and provides the compensation signal to a controller in the primary side circuit. A voltage value of the feedback voltage is lower than a voltage value of the bias voltage.
