Abstract
What is provided is a voltage-generating circuit that uses dynamic reference voltage to accurately control the step-up of a generated voltage. A voltage-generating circuitof the invention includes a charge pumpoutputting voltage Vpump, a regulator, and a controlling circuit. The regulatorincludes a comparatorand a comparator. The comparatorcompares voltage Vdivide generated by the charge pumpwith a reference voltage Vref, and outputs a comparison result CMP_OUT. The comparatorcompares voltage Vdividegenerated by the charge pumpwith a reference voltage VrefRRC with a controlled rising speed, and outputs a comparison result CMP_OUT. The controlling circuitcontrols the charge pumpbased on CMP_OUT and CMP_OUT.
