摘　　要：晶体振荡器作为基准频率源,在电子设备中发挥着重要作用。晶体振荡器对加速度具有敏感性,振动、冲击、离心力等作用均会导致其输出频率失稳。讨论了加速度影响晶体振荡器频率及相噪的机理,介绍了目前降低加速度效应的常用措施,并提出一种基于数字补偿系统的新方法。As the reference frequency source,crystal oscillator plays a critical role in the electronic equipments.Crystal oscillator is sensitive to the acceleration,such as vibration,concussion and centrifugal force,which would influence the stability of the frequency output.How acceleration affects the frequency and phase noise of crystal oscillator is discussed,some current measures of reducing the acceleration effects are introduced.A new method based on the digital compensating system is also brought up.

关 键 词：晶体振荡器 加速度灵敏度 数字补偿
