ABSTRACT:
A crystal-stabilized integrated-circuit oscillator which uses a filtered analog coupling to automatically disable the bias current to an auxiliary gain after startup. Positive feedback is used to ensure that the switchover is completed once it starts. Thus the device sizes and biases of the primary gain stage can be selected for very low-power operation, while assuring that the oscillator will always start-up whenever poser is valid.
