What is Strobed Periodic Noise simulation in SpectreRF

RFStuff

 Dear All,

 In SpectreRF documents I have come across "Strobed Periodic Noise simulation in SpectreRF" for Synchronous Jitter measurement.

But in Pnoise analysis I have not seen Strobed option.

So what is Strobed Periodic Noise simulation in SpectreRF ?

Kind Regards,

Parents

  • The tdnoise option (at the bottom of the pnoise form, where it says noise type - default is "sources") is the strobed periodic noise analysis.

    Note that for jitter you can also pick the jitter noise type; this uses tdnoise (for a driven circuit, or for an oscillator if you pick PM jitter rather than FM jitter) by identifying the points to sample the noise based on a threshold crossing.

    Regards,

    Andrew.
