Dynamic BJT Model
>>Basics>Circuit>Semiconductors Device Level
The BJT model is a modular model with definable simulation levels. Different simulation
depths can be selected for the electrical and thermal behavior of the model.
You can define two simulation levels for the electrical and three simulation levels for the thermal
behavior. Each level combination has a certain set of parameters. The values of them can
be defined in the model dialog. The component outputs are true of all types of the BJT models.
They are listed at the end of the model description. See also “Thermal Semiconductor Model”
on page 126 and “Temperature, Voltage, and Current Dependencies” on page 125..
