    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.

    摘要: A multi-channel display driver circuit incorporating modified D/A converters has a plurality of digital comparators connected to a number generator. Each digital comparator has an output, a digital data input and a reference input. The reference inputs of all digital comparators are connected to the number generator and the outputs are respectively connected to corresponding data channels of a display. By the proposed technique, each digital comparator obtains a unique non-sequence reference signal, and then compares it with the input digital data signal. Since the non-sequential signals are input to the reference input of the digital comparator, the overshoot distortion, the harmonic distortion and the electromagnetic interference problems are prevented. Therefore, the precise imaging can be obtained with this signal modulation technique in small circuit size.
