Abstract
A power saving circuit for an electronic device is disclosed. The power saving circuit includes a direct-current (DC) power supply, a sensing unit, and a control unit. The DC power supply is used for providing a DC current. The sensing unit, coupled to the DC power supply, is used for detecting the DC current and operating to generate a voltage signal according to the DC current. The control unit, coupled to the sensing unit, is used for determining whether a system circuit of the electronic device has a light load or a heavy load and generating an enable signal.
