You can find commonly two approaches for managing the stability of the crystal oscillator with temperature variants in the surroundings. They may be temperature control and temperature compensation. Temperature control… Thermistor Compensation: TCXOs may possibly involve a temperature sensitive resistor and that is a thermistor to evaluate the environmental temperature https://temperature-compensated-c93704.total-blog.com/details-fiction-and-temperature-compensated-crystal-oscillators-56297593
