Hello,
I am running PNoise analysis for my Injection-locked oscillator before and after injection. Before injection, it's just a VCO, and in SweepType field, I choose "relative". However, when I inject a signal, "relative" option gets me the same PNoise of the VCO, which is not reasonable. My question is, since ILO is a driven circuit, should Sweeptype be "Absolute" or "default", especially as their results are very reasonable? and what are the difference between the three options?
Thanks,
