    摘要： A driving circuit of a light emitting diode (LED), including a driving unit, a current pre-charging unit and a feedback unit, is provided. The driving unit outputs a driving power to drive the LEDs and outputs at least one first feedback signal according to the current conducted in the LEDs. The current pre-charging unit is coupled to an output of the driving unit to provide a current path to the driving unit and generates a second feedback signal. One of the at least one first feedback signal is selected to adjust the driving power when the enable signal is at a first logic level; the second feedback signal is selected to adjust the driving power when the enable signal is at a second logic level so as to maintain a current to drive the LEDs.

    摘要： A driving circuit, a decoding circuit and a decoding method thereof are provided. The decoding circuit includes an oscillator and a decoder including a frequency determining unit and a decoding unit. The frequency determining unit receives a clock signal and a data signal which is corresponding to DMX512 protocol, and samples one slot of the data signal according to the clock signal to generate a sample number corresponding to a slot period of the slot. Then, the frequency determining unit outputs a reference signal corresponding to the frequency of the clock signal according to the sample number. The decoding unit samples the data signal according to the clock signal and the reference signal to decode data carried on the data signal. The decoding circuit is able to sample the data signal correctly without disposing any external frequency adjusting element.
