Abstract
A voltage level control circuit controls a target slicing voltage level to slice a video signal by a target circuit. The voltage level control circuit includes a slicing circuit for sequentially slicing the video signal by a plurality of slicing voltage levels to correspondingly generate a plurality of first clock signals; a detection circuit for respectively detecting a plurality of phase differences between the first clock signals and a plurality of corresponding second clock signals to generate a plurality of detection signals; an oscillating circuit for generating the second clock signals according to the detection signals, respectively; and an adjusting circuit for determining whether to adjust the target slicing voltage level according to the detection signals corresponding to the slicing voltage levels.
