Modeling and Simulation for MEMS Design, Industrial Requirements

Neul R., Robert Bosch GmbH, DE

The development process of today’s products is dominated by demands like ‘product performance’, ‘quality, ‘time to market’, ‘development cost’, ‘development risk’ etc., while the products’ complexity is increasing. Design methods for MEMS devices are discussed, [...]

Starting Over: gm/Id-Based MOSFET Modeling as a Basis for Modernized Analog Design Methodologies

Foty D., Binkley D., Bucher M., Gilgamesh Associates, US

A method of interpreting MOSFET behavior is described which is more coherent for modern analog CMOS circuit design. This method supercedes the use of simple but antiquated equations in design, and replaces them with an [...]

An Investigation on Modeling and Statistical Simulation of Si-Ge Heterojunction Bipolar Transistors for Characterizing Their Dependence on Germanium Content

Sipahi L.B., Sanders T.J., Florida Institute of Technology, US

Although silicon is by far the most widely utilized manufactured semiconductor material, it is very poor in terms of mobilities of holes and electrons, which give rise to unacceptable low operation speeds. Far higher charge-carrier [...]

Modeling, Simulation and Comparative Analysis of RF Bipolar and MOS Low Noise Amplifiers for Determining Their Performance Dependence on Silicon Processing

Sipahi L.B., Sanders T.J., Florida Institute of Technology, US

In this study, an investigation into MOS (metal-oxide semiconductor) and bipolar LNAs (Low Noise Amplifiers) in terms of their circuit design and the electrical circuit parameters was conducted. As partially reported [1], we have been [...]

Modeling and Simulation of Single-Electron Multi Tunnel Junction Memory

Le Carval G., Le Royer C., Le Carval G., Le Royer C., Sanquer M., Fraboulet D., CEA-LET, FR

For optimization of Quantum-Dot-based Multi Tunnel Junction Memory (MTJM) [1], we propose an original compact model validated by physical simulations. We analyze the impact of physical and technological parameters (Temperature, dots density, geometries…) on writing [...]

A Study of the Behaviour of Magnetic Microactuators

Flynn M., Gleeson J.P., University College Cork, IR

The behavior of an idealized magnetic microactuator is modeled and analyzed. A two parameter mass-spring model is shown to exhibit a bifurcation from one to three steady states as the geometry of the device is [...]

Coupled-Energy-Domain Macromodeling of MEMS Devices

Casinovi G., Georgia Institute of Technology, US

This paper describes a systematic approach to the development of multi-energy-domain macromodels of MEMS devices. This approach is based on a particular form of the coupled algebraic-differential equations describing the dynamics of the device. All [...]

Analysis of Physico-Chemical Processes in an Amperometric Oxygen Biosensor

Krishnamoorthy S., Feng J.J., Makhijani V.B., Gao C., Choi J.W., Ahn C., CFD Research Corporation, US

Amperometric techniques are commonly used in lab-on-a-chip systems to sense various blood gas analytes such as H+, CO2, O2, etc. In the present study, a microchip-based amperometric biosensor, being developed as a part of plastic-based [...]

Complex Fluid Dynamics in BioMEMS Devices

Liepmann D., University of California-Berkeley, US

MEMS technologies promises to revolutionize health care by providing precise control of biological fluids for both diagnoses and treatments. For example, microneedles can be used for sample collection for biological analysis, delivery of cell or [...]
