J_PJFJFETP-channel Junction Field-Effect Transistor model (JFET) |
This information is part of the Modelica Standard Library maintained by the Modelica Association.
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.
The models from the package Semiconductors accesses to the package Internal where all functions, records and data are stored and modeled that are needed for the semiconductor models. The package Semiconductors is for user access, but not the package Internal.
