CRYSTAL OSCILLATOR Russian patent published in 2007 - IPC H03B5/32 

FIELD: electronic engineering.

SUBSTANCE: proposed crystal oscillator that can be used to produce electric signals regulated by crystal cavities whose equivalent resistance is over 500 kΩ at static capacitance of about 1 pF and resonant frequency over 6 kHz and has resistor-capacitor bridge circuit is provided with newly introduced inverting amplifier with parallel-connected resistor. Bridge-circuit output is connected to input of other inverting amplifier.

EFFECT: enhanced operating stability of crystal oscillator.
