M2_Card

Record for MOSFET level 2 parameters

 

Description

Parameters

Modelica Standard Library

Description

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.
