**5.3.2 Fitting Procedure**

In the previous section the most critical parameters for the intrinsic
*g _{m max}* have been identified. The results are also applicable
to the extrinsic characteristics. The basic problem of the fitting procedure
is, that the set of unknowns is large enough that a given characteristics
can be modeled by different combinations of geometry and model parameters.
For instance a certain current density

The characteristics used in the following are the drain current and
the gate capacitances versus the terminal voltages as well as electron
transport properties obtained from Monte Carlo simulations. This way important
parameters can be separated from each other and uncertainties can be reduced
substantially.
