when I use ahbt model to do the transient simultation.
I can't get the result that shows the Ic current increase by time tends to level off .
The simulation resule is immediately reach to steady current.
I want to know does this model can predice this trend?
which parameters can modify this trend?
Hello Yawen,
I suggest that you contact Tech Support and send your project so that they can analyze it fully. Basic comments
from an AHBT model expert are:
"If the user is using the default model card and instance, SelfTmod needs to be set to 1 for the self-heating to work. The default parameter has Rth=1000 and Cth=5e-10, and so the thermal time constant should be around 0.5usec."
You may want to check this on your model, but if it does not answer you question, please contact eesof_support@keysight com and someone will be happy to assist you.
