Abstract
A voltage compensation circuit and a control method thereof dynamically compensate a voltage drop caused by supplying power from a first power line to a function circuit. The voltage compensation circuit includes an amplifier, a detection module and a boosting module. The amplifier has an inverting input end coupled to the first power line and the function circuit to be supplied with a load voltage supplying to the function circuit, a non-inverting input end for being supplied with a reference voltage, and an output end coupled to the detection module to output a comparison signal. The boosting module is coupled between the detection module and the inverting input end of the amplifier. The detection module generates compensation voltage information according to the comparison signal. The boosting module outputs the compensation voltage to the inverting input end of the amplifier according to the compensation voltage information.
