    Abstract: A power supply circuit is adapted to an electronic device. The power supply circuit includes a drive circuit, a feedback resistor circuit, a battery module and a controller. The drive circuit receives a charger boost indication signal and generates a drive signal accordingly. The feedback resistor circuit has a feedback resistance value changing in response to the drive signal and receives a DC power supply to supply power to a system component. The battery module provides a battery power supply to the system component. The controller controls the battery power supply provided by the battery module according to the feedback resistance value. When the system component is operating in a heavy load state, the controller transmits the corresponding charger boost indication signal to the drive circuit, so as to reduce the feedback resistance value through the drive signal.

    Abstract: A signal analysis circuit and a signal analysis method thereof are disclosed. The signal analysis circuit includes a peak detector, a subtraction amplifying unit, and a compare unit. The peak detector obtains a peak value of a first voltage signal to generate a second voltage signal. The subtraction amplifying unit generates a compare voltage signal according to the second voltage signal, and amplifies a voltage value difference between the second voltage signal and the compare voltage signal to generate a third voltage signal. A peak-to-peak value of the third voltage signal is larger than a peak-to-peak value of the second voltage signal. The compare unit compares the voltage value of the third voltage signal and the voltage value of the compare voltage signal to generate an output voltage signal. In such a manner, a new signal analysis circuit can be realized.
