Abstract:
A buffer circuit applied to a source driver output stage circuit includes a buffer and a D-class amplifier. The buffer is coupled to an input voltage for accordingly outputting an output voltage. The D-class amplifier includes a comparator and a switch device. The comparator is for comparing the input voltage and the output voltage and accordingly outputting a comparison signal. The switch device is coupled to an operational voltage for adjusting the output voltage according to the comparison signal.
