1. An oscillator circuit device, comprising:
a resistor circuit comprising a first resistor disposed between a first supply voltage level and an output node;
a resistor-capacitor circuit comprising a second resistor and a switched capacitor circuit disposed between the output node and a second supply voltage level and connected in series, and a switch capable of discharging electric charges accumulated in the switched capacitor circuit; and
a comparator configured to compare a voltage level to be compared obtained from the resistor circuit with a predetermined reference to allow the switch to be opened and closed according to a comparison result,
wherein the switched capacitor circuit is disposed between the second resistor and the second supply voltage level and comprises two capacitors connected in parallel to each other to be alternately charged and discharged.
