NTF of frac-N PLL divider quantization noise
Jun 03rd, 2022, 12:07am
 
I couldn't really figure out why there is a Tref in the noise transfer function of the frac-n divider noise.

Anyway intuitive to understand this a bit better?

This is another diagram showing the same thing.

Is this Tref gain just to scale FFT results properly from sampling?
