yzs Post subject: question about VCO simulation in Cadence Unread
postPosted: Tue Mar 15, 2005 1:23 pm i just simulate a very
basic LC cross-coupled VCO in Cadence. trans analysis. It's
weird to me that the results is subjective to simulation time. say
when simulate 20ns, I can see the oscillation wave, while if i change
to 10ns or 30ns, the wave is gone and seems not oscillate at all.
And, the Oscillation start time point is varies with the simulation
time as well. Why is that? Is this related to simulation time
step? simulator used is specture. 0.18 RFCMOS thanks for
