ABSTRACT:
Power consumption is substantially reduced and constant frequency is substantially derived without regulating the supply voltage for an oscillator circuit of the type wherein a capacitor is recurrently charged to a threshold voltage from the supply voltage and is then discharged through a gate turn-off (GTO) device. A reference voltage level proportional to the supply voltage is applied at the control electrode of the GTO device and positive current is applied at that control electrode when the differential between the charge voltage level and the reference voltage level reaches a positive trigger level, while negative current is applied thereat when that differential reaches a negative trigger level.
