摘要: A built-in self-test (BIST) circuit for a liquid crystal display (LCD) source driver includes at least one digital-to-analog converter (DAC) and at least one buffer coupled to the respective DAC, wherein the buffer is reconfigurable as a comparator. A first input signal and a second input signal are coupled to the comparator. The first input signal is a predetermined reference voltage level. The second input signal is a test offset voltage in a test range.
