Hello every one
I have designed a 100GHz oscillator and in order to see how much power it can produce I run different analyses. The issue is that the output voltage is quite different when I use different analyses. The frequencies are similar but the amplitudes are totally different. I have used PSS with harmonic balance and also probe-based HB (these two simulation give very similar results). However when I use Transient, the amplitude of the node voltages is quite different (the frequency is very similar).
Which one can I trust?
Thank you very much,
Hamid
PS: I have couple of transmission lines whose model are coming from EM simulation in HFSS.
