Crystal oscillator |
摘要 |
A quartz crystal oscillator in which phase noise is reduced includes: a resonance circuit having a quartz crystal unit and a split capacitor connected to the crystal unit; a transistor for oscillation having its base connected to the node of the crystal unit and the split capacitor; an output line for connecting the mutual node of the split capacitor to the emitter of the transistor; a quartz crystal resonator that is inserted in the output line; and a temperature compensation mechanism for compensating the frequency-temperature characteristics of both the crystal unit and the crystal resonator.
