摘要：
In a Colpitts quartz oscillation circuit, large negative resistance values are obtained in a high frequency band, and in the GHz band in particular. In a piezoelectric oscillator having a Colpitts oscillator, a voltage control circuit, and a coupling capacitor that couples the Colpitts oscillator and the voltage control circuit, an output of the voltage control circuit is feed back to a collector of the Colpitts oscillator via the coupling capacitor.
