    Abstract: An electronic device includes an energy collection circuit, a rectifier circuit, and a control unit. The energy collection circuit receives an energy signal transmitted via transmission frequency from a wireless charger base. The rectifier circuit generates a drive voltage according to the energy signal. The control unit compares the drive voltage with a reference voltage, and compares the transmission frequency with a reference frequency. When the drive voltage is less than or equals to the reference voltage, or when the transmission frequency is lower than or equals to the reference frequency, the control unit outputs position deviation information. The electronic device detects the efficiency of the wireless charging, and reminds the user whether the position of the electronic device needs to be adjusted, which ensures an efficient charging.

    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.
