At last, the difference between FNPLL and NPLL frequency synthesizer's performance is discussed and analyzed theoretically, and it is testified in the experiment.

最后，对分数分频与整数频率合成器进行了理论上的分析和比较，并通过实验得到了验证。

This paper gives the design and experimental results of low noise NPLL frequency synthesizer and concludes that the passive loop filter is more suitable for low noise design than active loop filter.

介绍低相噪NPLL 频率综合器的设计及实验结果。提出用无源环路滤波器比用有源环路滤波器更好，可获得低相噪设计。
