ABSTRACT:
A delay-controlled relaxation oscillator includes a capacitance in the oscillator which is alternately charged and discharged. The change-over from charging to discharging is controlled by means of a comparator which compares the capacitance voltage with a reference voltage. The oscillator also includes switching means for reducing the power consumed by switching the power supply for the comparator from the power supply mode into a stand-by mode between two change-overs.
