Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Technology parameters of the junction field-effect transistor model.
In modelcards, that are typical for SPICE3, the so called technology parameters are stored. These parameters are usually set for more than one semiconductor device in a circuit, e.g., the temperature of a whole electrical circuit.
