LEVEL 54 BSIM 4.0 Model
• Since defaults are non-zero, every model parameter listed in
LEVEL 50 Model Parameters table should be set in the
.MODEL statement.
• Select one of two available parasitic junction diode models,
ACM and JUNCAP. JUNCAP=1 selects the Philips
JUNCAP model, JUNCAP=0 (default) selects the
Star-Hspice ACM model.
See “Using the Philips MOS9 Model in Star-Hspice” in the
Star-Hspice Manual.
LEVEL 54 BSIM 4.0 Model
The UC Berkeley BSIM 4.0.0 MOS model is the LEVEL 54
Star-Hspice model; it is designed for modeling sub-0.13
micron CMOS technology and RF high-speed CMOS circuit
simulation. LEVEL 54 uses the general model statement
described in “MOSFET Model Statement” on page 9-3.
BSIM4.0.0 has major improvements and additions over
BSIM3v3, including:
• A model of the intrinsic input resistance (Rii) for both RF,
high-frequency analog, and high-speed digital applications
• Flexible substrate resistance network for RF modeling
• A channel thermal noise model and a noise partition model
for the induced gate noise
• A non-quasi-static (NQS) model consistent with the Riibased
RF model and an AC model that accounts for the NQS
effect in both transconductances and capacitances
