一种具有触发误差削减功能的数字移相集成电路

A Digital Phase-Shift IC with Decreasing Triggering Error

介绍了一种新型数字移相触发集成电路的工作原理、内部结构和功能特点,给出了其移相范围和控制精度的计算方法。由于电网的频率不稳定,出现频率漂移。针对此问题,详细分析了触发误差的产生,提出了一种简单易行的减小触发误差的方法。与现在使用的锁相环同步技术相比,该方法具有明显的优势。

A new digital phaseshift IC is developed And its principle of operation,internal structure and function characteristics are dealt with in the paper The method for calculation of phaseshift range and control precision is described There is a frequency drift due to the unstable frequency of electricity network The generation of errors,especially the triggering error,is analyzed in particular And a new method is presented to reduce the triggering error,which is easier to follow than the existing PLL inphase method
