  • Re: Phase noise to phase jitter for square waves
     Edouard, I read your post once and again (and again). You seem very confident, and besides it is much easier to walk in a beaten path than build a new one, but I couldn't get myself conviced that you are right. However, at this point it I feel that it will not be appropriate to continue the discussion as it is since it seems that we ...

  • Re: Phase noise to phase jitter for square waves
    Edouard and Andrew, Thanks for the detailed response. A few comments: 1. How was the expression to oscillator signal as a sum of exponents/sines was developed? I'm not sure that it is so straight forward since a disturbed clock is no longer a periodic signal, thus some assumptions have to be performed in order to develop a Fourier series ...

  • Re: Phase noise to phase jitter for square waves
     I don't have any clear argument why it could be generalized, it just makes sense to me to say so. Anyway, I can say that (1 - Frank) the dominant noise source is not the oscillator but the stages that extract CMOS clock from the sine wave at the oscillator loop and (2 - Andrew) when I'm not neglecting the higher sidebands and ...

  • Re: Phase noise to phase jitter for square waves
     Andrew, Frank, Let me get back to my original claim before I answer your two latest comments. Let's leave the filtration aside for now. My claim was that it is enough  to look at the first harmonic's jitter when analyzing a square wave's jitter. Using what I just learnt on ponise -> jitter -> pm, I thought of the ...

  • Re: Phase noise to phase jitter for square waves
    Quoting:I think there are some assumptions you are making here which aren't necessarily correct. In general you should use the "jitter" noisetype if you want to measure jitter. There are two approaches - "FM" jitter (which uses a conversion from the PM part of the noise, as computed with ...

  • Phase noise to phase jitter for square waves
    Hi, I'm simulating a free running oscillator for jitter and I have the following question: I have to run a "PNOISE - sources" simulation in order to recieve phase noise, since I have to filter the phase noise before integrating in to extract jitter (in order to mimic a PLL / CDR transfer function). A few papers were written ...
