BSIM4_Model:BSIM4 MOSFET Model

The SPICE BSIM3 MOSFET model is translated to the ADS MOSFET BSIM3_Model. For translation information on the MOSFET device, refer to MOSFET Device.

For more information on the ADS model, place the model in a schematic and choose Edit > Component > Edit Component Parameters to view the model parameters. You can also click Help in the component editor dialog box for additional information.

Example SPICE Command Line:


.model nch nmos versiion=4.0.0 ...
