1. A voltage generation circuit, comprising:

  • a conversion circuit converting an input voltage to another voltage level and providing an output voltage after converting, to an output node;

    a resistor voltage-division circuit coupled to the output node, generating a voltage corresponding to the output voltage;

    a comparison circuit comparing the voltage generated by the resistor voltage-division circuit and a reference voltage; and

    a control circuit controlling the conversion circuit based on a comparing result of the comparison circuit,wherein the resistor voltage-division circuit comprises a capacitor device which is capacitively coupling at least one part of a resistor in the resistor voltage-division circuit to the output node, andwherein the capacitor device comprises a conductor portion extending from the output node and over the at least one part of a resistor.
