Abstract

PURPOSE: To secure the steady clamping for the oscillation output and thus to facilitate an easy IC formation by providing the clamping circuit to the output end of the phase inverse amplifier as well as to the output end of the crystal oscillator and then applying the resistance load to the output end of the crystal oscillator and the input end of the phase inverse amplifier each.
CONSTITUTION: Crystal oscillator 3 is connected between the input and the output of phase inverse amplifier 1 connected to resistance 2 for self-bias. Then the crystal oscillator consists of resistance 4 for fine adjustment of the frequency plus capacitor 5 also for fine adjustment of the frequency. The clamping is then given to the output of the crystal oscillator via the clamping diode comprising two silicon diodes 8 and 9 connected in parallel and backward to each other plus the potential generator circuit. the potential generator circuit applies phase inversion circuit 10, and the input end and the output end of circuit 10 are connected directly or via the resistance load. Thus the DC voltage can be obtained.
