JC,
It may not help you directly, but there is another figures of Oscillator
merit the perturbation projection vector, PPV. For more information, see
Frank Wiedmann's comment in the following e-mail,
http://www.designers-guide.org/Forum/YaBB.pl?num=1179739160/1#1or the following reference,
<<reference to chapter 2 of Hegazi, Rael, and Abidi (http://www.designers-guide.org/Books/dg-osc/index.html) was deleted by forum administrator>> The good news is that SpectreRF will directly output the PPV for a VCO. To save
the PPV, in the PSS window:
select "Oscillator" then "options", in the options window select "save osc ppv".
You can use the Results Browser to access the PPV.
Best Regards,
Sheldon
