振回路。[Claims for Utility Model Registration] A plurality of CMOS-configured inverters are connected in series, and the first-stage inverter on the input side and the output of a predetermined stage inverter are connected via a capacitor, and the duty cycle is determined according to the charging and discharging characteristics of the capacitor. In an oscillation circuit using a CMOS inverter that generates pulses by controlling a ratio, the input potential of the first stage inverter is connected between the capacitor and the input of the first stage inverter when the capacitor is charged or discharged.
An oscillation circuit using a CMOS inverter, characterized in that it is provided with switching means for changing the potential to a voltage sufficiently larger or smaller than the S operation threshold voltage.
