CRYSTAL OSCILLATOR FREQUENCY STABILIZATION DEVICE Russian patent published in 2005 - IPC

FIELD: radio electronics; crystal oscillators incorporating provisions for temperature compensation and thermostatic control.

SUBSTANCE: proposed device characterized in high Q-factor, flat frequency response characteristic, and steep temperature-frequency response characteristic has piezocrystal component and electronic circuit for exciting resonator in two modes; piezocrystal component is placed at angle of 10° 53' to X axis and minus 30 - 32° to Z axis of piezocrystal.

EFFECT: reduced dependencies of extremum position from cut angle with respect to reference mode and of transient resistance on temperature with respect to heat-sensing mode.
