ABSTRACT:
An oscillation circuit using a quartz oscillator. When the output level of the oscillation circuit falls, this output level change is detected and the reactance of the quartz oscillator is changed such that the circuit oscillates at a frequency which reduces the resistance of the oscillator. Hence, the oscillation of the circuit does not fall in level or stop regardless of temperature and other ambient conditions.
