ABSTRACT:
In a ring oscillator constituting an oscillating circuit, resistor circuits are used as delay circuits to be connected to respective inverters. That is, the inverters and the resistors are connected in series so that the resistor is provided between the adjacent inverters. With the arrangement, it is possible to provide an oscillating circuit which is less dependent on any of power supply voltages, temperatures, and manufacturing variations, while maintaining a characteristic in which the oscillating frequency decreases as an output voltage of a booster circuit increases.
