M2_Card
Record for MOSFET level 2 parameters
Description
Parameters
Modelica Standard Library
The M2_Card record holds the technology parameters of a level 2 Schichman-Hodges model for MOSFET transistors.
Parameters with value −1·1040 are special default values used to indicate the user has not selected a value.
All capacitor parameters must be assigned positive values. MapleSims engine does not currently handle the defective differential equation that occurs when the capacitance is zero.
