modelJ_PJFJFET
P-channel Junction Field-Effect Transistor model (JFET)
Extends from Modelica.Electrical.Spice3.Internal.JFET (Junction Field-Effect Transistor).
Information
J_PJFJFET is a P-channel junction field-effect transistor.
The junction field-effect transistor is derived from the FET model of Shichman and Hodges.
