Numerical Modeling of a Piezoelectric Micropump

Schlipf R., Haghighi K., Lange R., Purdue University, US

An effective description and an accurate understanding of any pumping mechanism is critical, especially of the micro scale. With the existence of a comprehensive and adaptable model, accurate preproduction predictions of performance are realized. Optimal [...]

Piecewise Perturbation Method (PPM) Simulation of Electrostatically Actuated Beam with Uncertain Stiffness

Juillard J., Baili H., Colinet E., SUPELEC, Department of Measurement, FR

We present a new approach to the simulation of uncertainties in micro-electromechanical systems, based on the same principle as perturbation methods. This approach is valid for large variations of the uncertainties and requires much less [...]

Circuit Modeling and Simulation of Integrated Microfluidic Systems

Chatterjee A.N., Aluru N.R., Beckman Institute, US

A combined circuit-device model for the analysis of integrated microfluidic system is presented. The complete model of an integrated microfluidic device incorporates modeling of the fluidic transport, chemical reaction, reagent mixing and separation. The microfluidic [...]

New Capabilities for Verilog-A Implementations of Compact Device Models

Mierzwinski M., OHalloran P., Troyanovsky B., Mayaram K., Dutton R.W., Tiburon Design Automation, US

Acceptance of a model requires its availability in main-stream simulators, yet it can be difficult to get a new model into commercial simulators. In this paper we present simulation results using a compiled Verilog-A architecture [...]

A Unified Mobility Model for Excimer Laser Annealed Complementary Thin Film Transistors Simulation

Lin H-Y, Li Y., Lin H-Y, Lee J.W., Chiu C-M, Sze S.M., Natl Nano Device Labs & Natl Chiao Tung Univ, TW

Excimer laser annealing technique has been proposed in the fabrication of low temperature polycrystalline silicon (LTPS) in the recent years, in particular for the applications to active-matrix liquid crystal display (AMLCD) [1]. In comparing with [...]

Spectral Analysis of Channel Noise in Nanoscale MOSFETS

Casinovi G., Georgia Institute of Technology, US

This paper describes an algorithm for numerical computation of the power spectral density (PSD) of channel noise in nanoscale MOSFETs. Noise generation phenomena inside the channel are modeled as random processes, represented by distributed sources [...]

Liquid Disintegration: Investigation of Physics by Simulation

Zeng J., Korsmeyer T., Coventor, Inc., US

Liquid disintegration includes the processes of formation of droplets and droplet fission. It is important in inkjet printing and in the miniaturization of biochemical analytical devices. This paper reports on an investigation of the mechanism [...]

Development and Characterization of a 2-D microchip-based Protein separation system

Feng J.J., Olazábal V, Olivares J.A., Sundaram S., Krishnamoorthy S., Iyer S., Los Alamos National Laboratory, US

Traditional methods in proteomics have relied on gel-based separation of proteins followed by directed cleavage of these proteins and mass spectrometry to measure the products. The emphasis on reliable, high-throughput analyses has led to the [...]

Surface Shaping by Ion Beams at Grazing Incidence: Simulations vs. Experiment

Stepanova M., Dew S.K., University of Alberta, CA

Miniaturization of electronic technologies highlights special approaches such as selforganization of nanostructures. Particularly, surface etching by ion beams at grazing incidence is of interest for applications, because it provides pronounced submicron size, self-organized ripples. Formation [...]

A Novel Simulation Methodology for Isotropic Gas Phase Etching

Bahreyni B., Shafai C., Card C.M., The University of Manitoba, CA

A novel methodology for the simulation of isotropic gas phase etching of a substrate is presented. In this method, individual substrate atoms are removed upon physical impingement of etchant gas molecules. The effects of different [...]
