Abstract
The article provides a theoretical limit assessment of the stability of a digital thermocompensated quartz oscillator with a temperature sensor based on two auxiliary quartz oscillators. The results are 7,5 ppb (for a restless environment) and 0,75 ppb (for a calm environment). Technical solutions are considered for obtaining a linear one-to-one dependence of the difference frequency value on temperature and increasing the steepness of this dependence. The proposed solutions allow obtaining a temperature measurement resolution of up to 0,001 ºС.
