| Abstract: | In order to improve the frequency performance of quartz crystal oscillator and reduce the temperature effect, on the basis of frequency-temperature specificity of quartz crystal oscillator, temperature compensation technology based on AT-cut crystal resonator with microprocessor （STC89C52RC）as core is proposed. System structure, compensation theory and hardware circuit are introduced, and the compensation results are given. The design has such advantages as simple structure, low power consumption. |
