High Voltage MOSFET’s Modeling Review

Ma Y., Jeng M-C, Liu Z., Cadence Design System, Inc., US

In this paper, different modeling solutions for HVMOS and LDMOS are discussed, current status of compact model development for HVMOS/LDMOS are reviewed. Macro models are widely used to model HVMOS and LDMOS devices. Different macro [...]

A Full-System Dynamic Model for Complex MEMS Structures

Rocha L.A., Cretu E., Wollfenbuttel R.F., Delft University of Technology, NL

For full characterization of a surface micromachined MEMS device, where the thickness of the moving layer is just a few times the gap size, the modeling has to take large-signal behavior and end effects into [...]

System Model for a Novel No Moving Parts Diffuser Valve Based Diaphragm Actuated Micro Pump

Banerjee D., Yano K., Bart S.F., Coventor, US

Analytical results for oscillating flow in a channel indicate regions of high shear stress close to the wall along with the flow reversal in the central portion of the flow at certain frequencies of actuation. [...]

Compact Large-Displacement Model for Capacitive Accelerometer

Veijola T., Kuisma H., Lahdenperä J., Helsinki University of Technology, FI

A compact large-displacement model for a gas damped capacitive accelerometer is presented. The gas-film model has been derived from the modified nonlinear Reynolds equation, where the in uence of the gas rarefaction is included. The [...]

A Technique for Extraction of Macro-Models in System Level Simulation of Inertial Electro-Mechanical Micro-Systems

Zaman M.H., Bart S.F., Rabinovich V.L., Ghaddar C.K., Tchertkov I., Gilbert J.R., Microcosm Technologies, Inc., US

This paper presents a comprehensive CAD environment for MEMS/MST design. The design flow includes MEMS mechanical schematic entry, parameterized cell layout generation, LVS style error checking, lumped parameter macro-model generation, and system level modeling of [...]

Reduced-Order Modeling of Lorentz Force Actuation with Modal Basis Functions

Varghese M., Rabinovich V.L., Senturia S.D., Massachusetts Institute of Technology, US

We present a method for generating dynamic reduced-order models for Lorentz force actuation in microelectromechanical systems (MEMS). These models, derived from a set of meshed simulations, are analytical representations of the magnetic co-energy of a [...]
