BSIM
Encyclopedia
BSIM refers to a family of MOSFET
transistor models for integrated circuit design. Accurate transistor models
are needed for electronic circuit simulation
, which in turn is needed for integrated circuit design
. As the devices become smaller each process generation (see Moore's law
), new models are needed to accurately reflect the transistor's behavior.
Commercial and industrial analog simulators (such as SPICE
) have added many other device models as technology advanced and earlier models became inaccurate. To attempt standardization of these models so that a set of model parameters may be used in different simulators, an industry working group was formed, the Compact Model Council
, to choose, maintain and promote the use of standard models. BSIM models, developed at UC Berkeley are one of these standards. They include BSIM3, BSIM4, and BSIMSOI.
Other models supported by the council are PSP, HICUM, and MEXTRAM.
MOSFET
The metal–oxide–semiconductor field-effect transistor is a transistor used for amplifying or switching electronic signals. The basic principle of this kind of transistor was first patented by Julius Edgar Lilienfeld in 1925...
transistor models for integrated circuit design. Accurate transistor models
Transistor models
Transistors are simple devices with complicated behavior. In order to ensure the reliable operation of circuits employing transistors, it is necessary to scientifically model the physical phenomena observed in their operation using transistor models. There exists a variety of different models that...
