BSIM1_Model:BSIM1 MOSFET Model

The SPICE BSIM1 MOSFET model is translated to the ADS MOSFET BSIM1_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 level=13 rsh=0 js=0 ...
SPICE Dialect and Netlist Syntax:

Spice2/3:

.model mname NMOS | PMOS LEVEL=4 [param=value]*

PSpice:

.model mname NMOS | PMOS LEVEL=4 [param=value]*

HSpice:

.model mname NMOS | PMOS LEVEL=13 [param=value]*

ADS Netlist Syntax:

model mname MOSFET NMOS=[0|1] PMOS=[0|1] Idsmod=4 [param=value]*

ADS Schematic Symbol:

Model Parameters:

For information on parameter format, refer to Using Parameter Mapping Tables to Understand a Translation.

Comments:

Tox > 1 is in angstroms in HSpice. Translator will convert it to um.

ADS does not support NRD, RDC, NRS or RSC MOSFET parameters. If RD or RS are not given, they will be calculated as follows:

RD=NRD*RSH+RDC

RS=NRS*RSH+RSC
