A History of MOS Transistor Compact Modeling
The MOSFET (Metal-Oxide-Silicon Field-Effect- Transistor) or MOS Transistor (MOST) is a three dimensional electronic device. It operates on the conductivity modulation principle in a thin semiconductor layer by a controlling electric field to give amplifying [...]
Vector Potential Equivalent Circuit for Efficient Modeling of Interconnect Inductance
We present a compact topology for inductive parasitics, using the vector potential as a state variable. The model is local, i.e., only coupling between neighboring wires is explicitly modeled. However, the topology accounts for long-range [...]

Physical Modeling of Substrate Resistance in RF MOSFETs
A simple and accurate method is presented for extracting the substrate resistance of RF MOSFETs. The extraction results for 0.18 um MOSFETs are shown for various bias conditions. The dependence of the extracted substrate resistances [...]

Scholten A.J., Tiemeijer L.F., van Langevelde R., Zegers-van Duijnhoven A.T.A., Havens R.J., Zegers-van Duijnhoven A.T.A., Venezia V.C., Klaassen D., Philips Research Laboratories Eindhoven, NE
The RF noise in 0.18um CMOS technology has been measured and modeled. Compared to long-channel theory we find only a moderate enhancement of the drain and current noise for short-channel MOSFETS and, due to the [...]
Compact Bipolar Transistor Modeling – Issues and possible solutions
Recently, several advanced compact bipolar transistor models ave become available to the design community. For existing technologies, these models (and their internal formulation) are believed to offer sufficient flexibility and accuracy, especially compared to the [...]

A Physics-Based Compact Model for Nano-Scale DG and FD/SOI MOSFETs
A process/physics-based compact model (UFDG) for double-gate (DG) MOSFETs is overviewed. The model, in essence, is a compact Poisson-Schrödinger solver, including accountings for short-channel effects, and is applicable to nano-scale fully depleted (FD) SOI MOSFETs [...]
