Hi all,
seems to have many problems from VCO simulation
I'm simulating a VCO and I found an error from PSS.
From my simulation, in transient analysis, I found that
the VCO oscillates at 2.8 GHz (by measuring the period
of the output waveform). But from PSS, it shows that
the oscillating frequency is 3.5 GHz !!! How come ???
I tried to set many different "tstab" and different time
interval (tstart tstop) in transient simulation, but PSS
always shows 3.5 GHz !!
Could anyone explain me about this problem and how
to solve it,
Thank you all in advance,
Alez
