LEVEL1_Model:LEVEL 1 MOSFET Model
The Spectre Level 1 MOSFET (mos1) model is translated to the ADS MOSFET LEVEL1_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 Spectre Command Line:
- model nchmod1 mos1 vto=0.78 gamma=0.56 kp=0.8675e-4 tox=0.21e-7 nsub=0.21e17 ld=0.55e-6 capmod=yang vmax=4e5 theta=0.19 cbs=11e-15 cbd=10e-15 lambda=0.1
Spectre Netlist Syntax:
- model mname mos1 type=[npn|pnp] [param=value]*
ADS Netlist Syntax:
- model mname MOSFET NMOS=[0|1] PMOS=[0|1] Idsmod=1 [param=value]*
ADS Schematic Symbol:
Model Parameters:
For information on parameter format, refer to Using Parameter Mapping Tables to Understand a Translation.
