Abstract: A dual decoder for a wireless charging receiver and a wireless charging receiver using the same are provided. The wireless charging receiver includes a resonant circuit, a rectifier circuit and a dual decoder for the wireless charging receiver. The rectifier circuit coupled to the resonant circuit converts wireless energy received by the resonant circuit into a direct current. The dual decoder includes a frequency decoding circuit and a voltage amplitude decoding circuit. The frequency decoding circuit performs decoding according to a frequency of a voltage of the resonant circuit to obtain an instruction of a wireless transmitter. The voltage amplitude decoding circuit extracts a carrier on the voltage of the resonant circuit through a filter, and decodes the carrier into the instruction of the wireless transmitter. With the complementary of two-way decoding, the communication system becomes robuster.
