Modeling of Piezoelectric MEMS Using the Finite Cloud Method
In this paper we present a meshless based Finite Cloud Method (FCM) for the numerical solution of partial differential equations (PDEs) governing piezoelectricity. Using a point distribution, FCM constructs interpolation functions without assuming any connectivity [...]
Intelligent Automatic Meshing of Multilayer CMOS Micromachined Structures for Finite Element Analysis
In this paper, we describe an automatic technique for meshing multilayer CMOS micromachined structure for Finite Element Analysis (FEA) from device layout. The technique is based on a 3D canonical representation of the different CMOS [...]
Transient Electromagnetic Behaviour of Multiply Contacted Interconnects
This paper presents a methodology for the analysis of the transient electromagnetic behavior of multiply contacted interconnects. It is shown that for applications with high switching frequencies and high pulse repetition rates with subsequent steep [...]
Investigation of Tetrhedral Automatic Mesh Generation for Finite-Element Simulation of Micro-Electro-Mechanical Switches
Simulation of micro-electro-mechanical systems (MEMS) typically involves the requirement to mesh complex 3-D representations of the geometry. Since proper manual or semi-automated mesh generation requires significant user time and knowledge, there is great interest in [...]
Numeric Aspects of the Simulation of Two-Dimensional Ferroelectric Hysteresis
Simulation of ferroelectric hysteresis allows the analysis of nonvolatile memory cells which are based on ferroelectric materials. We give an overview of our algorithm for the calculation of effects caused by field rotation. Implementation of [...]
A Design Tool for Inductive Position and Speed Sensors via a Fast Integral Equation Based Method
This paper describes using 3D integral equation based simulation in combination with simulation managment to provide a design tool for an eddy-current inductive position and speed sensor under development at CSEM Microsystems. Both the frequency [...]
Analytic 3D Greens Function Approach to Scattering and Diffraction from Patterned and/or Imperfect Multilayers
The 3D electromagnetic Greens function Gij(x,x) for planar multilayers is constructed from the eigenmodes of Maxwellís equations in the multilayer structure. Other approaches hav been used to derive the Greens function and the derivation here [...]
Parallel Domain Decomposition Applied to 3D Poisson Equation for Gradual HBT
García-Loureiro A.J., Pena T.F., López-González J.M, Prat Viñas Ll., Univ. Santiago de Compostela, ES
This paper presents the implementation of a parallel solver for the 3D Poisson equation applied to gradual HBT simulation in a memory distributed multiprocessor. The Poisson equation was discretized using a finite element method (FEM) [...]
Optimum Algorithm for Electronic System Design
The evaluation of operations number for the system design has been done for general design strategy. More general methodology for the system and circuit design was elaborated by means of optimum control theory formulation. This [...]
Analysis of Unstable Behavior Occurring in Electro-Mechanical Microdevices
We analyze the instability which is inherent to electrostatically driven microdevices. Further, we propose a homotopy method to overcome this difficulty during simulation of these devices. Starting from a simplified model, the governing differential equations [...]
Optimal Time Stepping in the Thermo-mechanical Finite Element Simulation of IGBTs Modules
In the analysis of the thermo-mechanical response of the wire bond connection found e.g in IGBTs modules, it has been found that the level of stresses are within the plastic range [1]. Therefore an incremental [...]
