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.

Abstract: An LED device with built-in fast self-test circuit includes at least one LED unit, a data shift and latch register, a control unit, at least one multiplexer, and an LED driver unit. The data shift and latch register receives a serial data signal. The control unit receives the serial data signal to detect whether there is normal data transmission based on the serial data signal. When there is no data transmission, the control unit enables a multiplex control signal. The multiplexer is connected to the control unit and the data shift and latch register. According to the multiplex control signal, the multiplexer selects the control unit or the data shift and latch register as an output. The LED driver unit is connected to at least one LED unit and the multiplexer to drive the LED unit based on the output of the multiplexer.
