PN function in Visualizaion & Anaysis XL Calculator

JaeWook

Hi,

I have a question about the PN function, available in the Calculator.

 

Is an output phase noise spectrum is a signle sideband or a double sideband spectrum?

To avoid any confusions, I mean the 'double sideband' by a spectrum 3dB more than the 'single sideband' in magnitude.

 

Thanks for any comment or answers.

  • Dear Andrew,

    Thank you for the reply.

    What I try to do is to make a transient phase noise model of a VCO in veriloga. In order to verify my veriloga model by comparison, I need to run both a pss/pnoise analysis in transistor level and a transient analysis in behavioral level. Then I compare two spectrums from the pnoise and the transient analyses. That is why I care about the PN function as much as other pnoise functions.

    I appreciate your help again, and if any futher comment or suggestion possible, please let me know.
