WIRELESS CHARGING CIRCUIT AND CHARGING BOARD THEREOF
First Claim
1. A wireless charging circuit coupled to an oscillation unit configured to generate a differential signal, said wireless charging circuit comprising:
- a balun unit coupled to said oscillation unit;
a higher-order filter unit coupled to said balun unit; and
a differential unit coupled to said higher-order filter unit and a transmission coil;
wherein said oscillation unit transmits said differential signal to said balun unit, said balun unit converts said differential signal into a converted signal to be transmitted to said higher-order filter unit, said higher-order filter unit filters said converted signal to output a filtered signal to said differential unit, and said differential unit converts said filtered signal into a differential output signal to be outputted by said transmission coil.

Abstract
A wireless charging circuit coupled to an oscillation unit. The wireless charging circuit includes a balun unit, a higher-order filter unit and a differential unit. The balun unit is coupled to the oscillation unit. The higher-order filter unit is coupled to the balun unit. The differential unit is coupled to the higher-order filter unit. The differential unit is coupled to a transmission coil. The oscillation unit issues a differential signal to the balun unit, and then the balun unit converts the differential signal into a converted signal to be transmitted to the higher-order filter unit. The higher-order filter unit filters the converted signal to output a filtered signal to the differential unit. The differential unit converts the filtered signal into a differential output signal to be outputted by the transmission coil.
