Dear all,
Hi!
I'm trying to do a Harmonic Balance (HB) Large-Signal S-Parameter (LSSP) simulation to figure out the input impedance of a nonlinear circuit.
Through this simulation, what I want to know is the large-signal S11 only (not S12, S21 and S22).
So, I have simulated with only single port (PORT0) at input, but LSSP simulation is terminated and output log shows following text.
" Analysis `hb' was terminated prematurely due to an error "
The LSSP simulation does not proceed without second port.
Should I use floating second port (which is not necessary for my circuit) to succeed the LSSP simulation?
Does the LSSP simulation really need two ports?
Below figure is my HB LSSP simulation setup.
Additionally, Periodic S-Parameter (PSP) simulation using HB is succeeded with only single port.
What is the difference between PSP and LSSP simulations?
