PARAM.MES setup file extracts Idlin and Vtci by using the 4155/4156 User
Function and Auto Analysis Function. These parameters are extracted with the
following conditions:
Idlin:
Gate voltage VG=5 V
Substrate voltage VB=0V
Vtci:
W/L Ratio (Gate width/Gate length ratio) =10
μm/1 μm
For changing the conditions, refer to “Modifying the Program” on page 9-35.
