MOSFET models

Circuit simulation programs such as SPICE use more sophisticated MOSFET models that contain many parameters. Often the BSIM models are used. For low power and high-frequency analog design, sometimes the EKV model is used. An advantage of the EKV model is that it has fewer parameters than the BSIM models. Nevertheless, there are many parameters to specify. The parameters to specify a n-MOSFET and a p-MOSFET in a 90 nm CMOS process are shown below.

*** EKV v301.01 parameters for 90nm CMOS (C) EKV3 15-FEB-09
****************************************************************************
* Intrinsic paremeters for a n-mosfet are based on [1] and *NOT* intended
* for use in real design. The set includes all intrinsic model parameters.
* Use of extrinsic model parameters and models (series resistance,
* junction currents and capacitances) is in general simulator-dependent.
* Parameters do *NOT* correspond to a particular technology but
* have reasonable values for standard 90nm CMOS.
