| 摘 要： | 主要从标准秒脉冲信号产生原理和秒脉冲信号外同步原理入手,论述了秒脉冲信号相位微跃原理。针对一般相位微跃技术的不足,提出了一种基于高速比较器和DA转换器的相位微跃技术,并给出了硬件系统设计方案。通过理论分析,该方法的调整精度可达到10ps量级。

| Abstract: | Principle of producting standard pulse-per-second(PPS) signal and PPS signal outer synchronization were introducted firstly in this paper,and then phase micro step principle of PPS was discussed.There is insufficiency in the general phase micro stepper technique,so we present a new phase micro stepper technique based on high speed comparator and DA converter and provied the design scheme of hardware system.Stepper precision of this technique can achieve 10 ps order by theoretical analysis. |
