drplJitter function help

debaabed

Hi,

When running pmjitter based phase noise measurement. The drplJitter function is used to obtain a sec/sqrt(Hz) plot. Where can I find help for this function?

drplJitter(?result "pnoise_pmjitter" ?unit "Second" ?k 1 ?event 0)

1) What does "k" represent in the above function?

2) Is there a way to obtain SSB phase noise plot in dBc/Hz using pmjitter?

Thanks

    1. k is the number of cycles that the jitter is accumulated over. The function is documented in the help - see Virtuoso Analog Design Environment L SKILL Reference -- 13 - drplJitter (I found this by searching for drplJitter on Cadence Online Support - but you should be able to find it in cdnshelp too).
    2. No, however in IC617 ISR17 (and later) together with SPECTRE171 you can now find the "edge phase noise" after running a Jitter (sampled) analysis (the new reformulation of the pmjitter analysis) - this is available on the direct plot form.

    Regards,
