Phase noise and normal noise are related, as their spectra are the same except that phase noise does not include power in its equation. This clarifies that while phase noise and normal noise appear similar, phase noise measurements do not account for power. Measuring phase noise requires specialized techniques compared to normal noise measurements due to issues with normalization and shape correction.

1. Noise vs phase noise relation

2. Are normal noise and phase noise same?
• What is the equation that tells about the relation

3. You can see that phase noise spectrum and
votlage spectrum are same withonly difference
being in the spike in voltage spectrum
The equation on the left is the fundamental equation

4. Both are same except that sout(f) has power in it and phase noise
doesn’t have this as highlighted in the box
This cleared a big confusion in my head
This is next level … Razavi is great
and
same

5. Why cannot we noise spectrum analyzer for
phase?

6. Normalization & shape correction are issues
