Title: High stability piezoelectric oscillator
Inventor: SATO TOMIO
IPC: H03B5/36
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To suppress an unnecessary vibration frequency and to prevent a jump phenomenon to a B mode by setting the parallel resonance frequency of the composite circuit network of an inductance and a capacitance which are inserted/connected into an oscillation loop, around the unnecessary vibration frequency of an oscillator. SOLUTION: A circuit which is connected to a path in the case of a main vibration C mode frequency and which is attenuated in the case of a B mode frequency is added to the feedback circuit of an oscillator. When the circuit constant of the composite circuit network of division capacitors C1-C4 and inductance (L1+Z) is changed and an oscillation circuit negative resistor is simulated, a circuit where only a C mode is oscillated and B mode oscillation is completely suppressed is obtained. The series resonance frequency of the composite circuit network is matched with the C mode frequency and the parallel resonance frequency to the B mode frequency. A negative resistance characteristic can be set to a desired one by adjusting an inductance (L1+Z) value.  At the time of manufacturing a high stability crystal oscillator, the deterioration of oscillator frequency stability in a frequency jump phenomenon is prevented.
