  • Re: VCO jitter calculation using PNOISE simulation
    Your comment is really helpful to understand PSS sim. Thank you for your reply, Andrew   I read the app note you suggested(for version MMSIM6.0, March 2006), and I'm little confused about k-cycle jitter. From the note, section "Synchronous Jitter Versus Accumulating Jitter", autonomous circuits, e.g. VCO have only ...

  • VCO jitter calculation using PNOISE simulation
    Hi all, I have two questions about pnoise jitter calculation in SpectreRF. 1. What is the meaning of Freq. Multiplier in jitter calculator? 2. What is the optimum integration range of phase noise for jitter calculation? Actually, I posted about similar subject last year, but I'm still confused..... : ...

    Frank. I appreciate your help. Your replies were really helpful. Unfortunately, I still have some questions. Can you give me more answers? 1. From your suggested documents, meaningful jitter for autonomous circuit is Jc. However in 10page "Jitter measurements using SpectreRF application note" by Cadence, Jc is timing difference ...

  • Re: Jitter cacluation from phase noise??
    I really appreciate your reply, Frank. Your reply was been so helpful to understand the jitter measuring method. In conclusion, when I want to know accumulation jitter of free running VCO for driving ADC, I should do following steps. 1. Pnoise analysis with frequency sweep from 0Hz to f0/2 should be performed. 2. Maximum sideband of ...

  • Re: Jitter cacluation from phase noise??
    Hello Frank, Thank you for your reply. I read suggested posts and found your answer.(http://www.designers-guide.org/Forum/YaBB.pl?num=1092399689/22#22  reply #20) In this post, you mean the frequency sweep range of pnoise simulation for driven circuit is 0Hz(or very low freq.)~Fout/2. Am I right? Maybe, it'll be same in ...

  • Re: Jitter cacluation from phase noise??
    Hello Andrew, Thank you for your detailed reply. It made me clarify the concept of PSS and PNOISE simulation, especially the meaning of number of harmonics, maximum sidebands, pnoise frequency sweep range. Well, still I'm confused about phase noise integration range to extract jitter. Assume one designs a free running VCO and this VCO ...
