Title:
HARTLEY PIEZOELECTRIC OSCILLATOR
Document Type and Number:
Japanese Patent JP2004048689
Kind Code:
A
Abstract:
To provide a Hartley crystal oscillator which is suited to high frequency oscillation and does not generate unwanted resonance.
The Hartley piezoelectric oscillator is provided with a piezoelectric vibrator parallel connected between a collector and an emitter of a base-grounded transistor for an amplifier circuit, a parallel circuit composed of a capacitor and a resistor inserted and connected between the emitter of the transistor and the ground, a parallel circuit composed of a capacitor, a resistor and inductance inserted and connected between the collector of the transistor and a power source, and a bypass capacitor for grounding connected to the power source.
