DEVICE FOR THERMAL COMPENSATION OF QUARTZ GENERATOR Russian patent published in 2013 - IPC H03B5/04 H03B5/32 

FIELD: electricity.

SUBSTANCE: device for thermal compensation of a quartz generator comprises a quartz generator, a frequency divider, the first counter, the second counter, the first trigger, the second trigger, a register, the first and second summators, a blocking circuit, resistors, a Schmitt trigger, a capacitor, a thermistor, a microcontroller with the first group of inputs and the second group of inputs.

EFFECT: higher accuracy due to taking into account individual features of a temperature-frequency characteristic of each specific quartz generator, possibility to apply a quartz generator, having any form of a temperature-frequency characteristic out of the possible ones and operating on any harmonic.
