Proper Orthogonal Modes for Macromodel Generation for Complex MEMS Devices

Lin W.Z., Lee K.H., Lim S.P., Institute of High Performance Computing, SG

In this paper, a novel method for macromodel generation for the dynamic analysis of structurally complex MEMS devices is developed by making use of proper orthogonal decomposition (POD) and classical component mode synthesis (CMS). The [...]

Lin J., Kiat Seng Y., Jian Guo M., Manh Anh D., Nanyang Technological University, SG

The accurate method to extract a small-signal subcircuit model of MOSFET’s based on BSIM4 is presented, a novel approach to determining the parasitic inductances by Z-parameters, the intrinsic terminal resistance and capacitance by Y-parameters are [...]

Unified Length-/Width-Dependent Drain Current Model for Deep-Submicron MOSFETs

Chiah S.B., Zhou X., Lim K.Y., Nanyang Technological University, SG

The motivation of this work is to develop a unified geometry-dependent drain current (Ids) model for the entire range of drawn length (L) and drawn width (W) without binning, considering all important short-/narrow-channel effects including [...]

Unified Length-/Width-Dependent Threshold Voltage Model with Reverse Short-Channel and Inverse Narrow-Width Effects

Chiah S.B., Zhou X., Lim K.Y., Nanyang Technological University, SG

The objective of this work is to develop a unified geometry-dependent scalable threshold voltage (Vt) model for the entire range of drawn length (L) and drawn width (W) without binning, including reverse short-channel effect (RSCE) [...]

A Technology-based Compact Model for Predictive Deep-Submicron MOSFET Modeling and Characterization

Zhou X., Chiah S.B., Lim K.Y., Nanyang Technological University, SG

This paper presents new development results of our compact model (Xsim) for deep-submicron MOSFETs. Although a threshold-voltage-based and source-referenced regional model, Xsim meets the basic requirements of continuity (to third-order derivatives), scalability (entire geometry range), [...]

Design of Performance-Enhanced Fabry-Perot Micro-Cavity Structure With a Novel Single Deeply Corrugated Diaphragm

Wang W.J., Lin R.J., Guo D.G., Nanyang Technological University, SG

The silicon micromachining technique has been successfully applied to the fabrication of miniature Fabry-Perot sensors. This kind of sensor detects changes in optical path length induced by either a change in the refractive index or [...]

Simulation of a Polymer Drop in a Shear Field with Dissipative Particle Dynamics Method

Chen S., Phan-Thien N., Fan X.J., Khoo B.C., National University of Singapore, SG

In the present study, the dynamics of polymer drops in micro channel under both steady state and transient shear flow conditions are investigated using Dissipative Particle Dynamics method. The polymer drop is made from finitely [...]

Simulation and Optimization of Tesla Valves

Truong T-Q, Nguyen N-T., Nanyang Technological University, SG

Tesla valve is a no-moving-parts valve. It has many advantages over conventional checkvalves in microscale. However, there has been very few literatures discussing its optimization. Systematic construction of the valve’s geometry has not been reported. [...]

Simulation of Self-Assembly of Quantum Dots in Superlattices

Liu P., Wang Y.Y., Lu C., Institute of High Performance Computing, SG

The self-organization of three dimensional quantum dot superlattices that spontaneously form during heteroepitaxial growth is investigated by using a three dimensional kinetic model. The model predictions show that the multilayer arrays of quantum dots can [...]

Studies on a DNA Double Helicoidal Structure Immersed in Viscous Bio-Fluid

Lim C.W., Shu J-J, Nanyang Technological University, SG

The paper aims at extending, utilising and generalising research in nonlinear dynamics of (i) spiral/helicoidal structures, and (ii) viscous, low speed fluid to biomechanical DNA fluid-structure interaction. Employing a nonlinear helicoidal model, the energy stored [...]
