HB- Simulation in ADS

Hi!
I want to design a power amplifier and I know one of the simulations which should be run is HB simulation. I have started with the test circuit of the transistor. after finishing this step I tried to run HB- simulation. But for some reasons it couldn't be converged. I don't know exactly what is the source of these errors. sometimes it complains there is a problem with DC and some other times small internal timestep.

Does anyone have any comments?

Zahra

HB Simulations are a bit tricky so you have to check the simulation setup, active devices models', circuit topology etc. Unless you haven't provided the whole project file with models, there will be just some intuitive help.

Hi!
Thank you for the reply. So could I send to you the ADS file of my simulation?

Regards,
Zahra
