recordModelcardJFET
Record for the specification of modelcard parameters for JFET
Extends from Modelica.Icons.Record (Icon for records), Modelica.Electrical.Spice3.Internal.ModelcardJFET (Record with technology parameters (.model)).
Information
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.
