Abstract

PURPOSE: To obtain an oscillation output with its duty cycle and peak value stabilized by switching and connecting a stabilizing power supply for different voltages to the output terminal of an oscillator circuit by a switching circuit which is switched by the output of an astable multivibrator.
CONSTITUTION: The oscillator circuit, equipped with astable multivibrator 1, switching circuit SW2 driven by its output, and stabilizing power supply 4 for output voltage VOH and stabilizing power supply 5 for output voltage VOL connected alternately to output terminal 3 by SW2, is driven by the voltage at output terminal 3 fed back to multivibrator 1. The peak value of the output voltage of this circuit is equivalent to outputs of power supplies 4 and 5, so that it can be made extremely stable. In addition, the duty cycle depends upon the period of multivibrator 1, but since this astable multivibrator operates by the output-terminal voltage with its peak value stable, the duty cycle becomes stable as well.
