ABSTRACT:
A CPU core voltage supply circuit includes a reference voltage generator, a differential operation amplifier, a power element, a feedback circuit and a first capacitor. The reference voltage generator outputs a first reference voltage. The differential operation amplifier has a positive input end, a negative input end and an output end. The positive input end is connected to the reference voltage generator for receiving the first reference voltage. The power element has a receiving terminal and a current output terminal. The receiving terminal is connected to the output end of the differential operation amplifier. The feedback circuit is connected to the current output terminal and outputs a feedback voltage to the negative input end of the differential operation amplifier. The first capacitor has an end connected to the current output terminal of the power element and the other end receiving a first voltage, thereby providing a CPU core voltage.
