A Simulation-Based Hybrid Optimization Technique for Low Noise Amplifier Integrated Circuit Design Automation

Li Y., Yu S-M., National Chaio Tung University, TW

In this paper we propose an intelligent simulation-based optimization technique for designing low noise amplifier (LNA) integrated circuits (ICs). Based on a genetic algorithm (GA), the Levenberg–Marquardt (LM) method, and a circuit simulator, the hybrid [...]

Transient Analysis of Snap-through Behavior of a MEMS Optical Switch

Huang Y-Y., Yang Y-J, National Taiwan University, TW

In this work, we present the study of the transient behaviors of the bi-stable mechanism used for a MEMS optical switch. The major part of the bi-stable mechanism consists of two constrained curved structures (the [...]

Optimization of Disk-type Piezoelectric Transformers

Kuo C-W, Kang C-Y., Huang Y-Y., Lee C-K, Yang Y-J, National Taiwan University, TW

In this work, we present the optimization of two disk-type piezoelectric transformers (PTs) by using the elite Genetic Algorithm (GA) and the finite-element solver, NTUPZE. The design goal is to optimize the voltage gain as [...]

The effect of damping for the rate of flow in the micropump

Lan W.P., Chang J-S, National Taiwan University, TW

This research is about identifying the optimal working frequency for valveless pump and comparison with experiment data. The fluid-solid membrane brings about different mode change as the work frequencies change. When the micropump work at [...]

Study of Thermal Efficiency Optimization in a Twin-bubble MEMS Micro-injector

Tang H-K, Tseng F-C, Wang W.W., Lee C-K, Lee I.Y., Lee K., Lee C-K, Lee I.Y., Lee K., Lee C-K, Lee I.Y., Lee K., BenQ Corporation, TW

In this paper, the methodology of design optimization to achieve optimal thermal efficiency of a twin bubble MEMS micro-injector is reported. This twin bubble back shooting structure can reduce the problems of crosstalk and satellite [...]

Nanotopography-controlled Cell Life and Death

Huang G.S., Su C-W, National Chiao Tung University, TW

NIH-3T3 cells were grown on nanodot arrays to investigate how cells respond to nanolandscape. The nanodot arrays consisted nanodot of diameters ranging from 10 to 200 nm which were fabricated by AAO processing on Ta-coated [...]

Chen P.Y., Ho K.C., National Taiwan University, TW

In this work, the major contribution is fabricating a uric acid (UA) biosensor based on molecular imprinted technique using a novel conducting polymer. Calibration curves were depicted according to the amperometric detection of steady current [...]

An amperometric on-chip glucose biosensor based on enzyme entrapment with pre-reaction to lower interference in a flow injection system

Nien P.-C., Huang M.-C., Chang F.-Y., Ho K.C., National Taiwan University, TW

In this study, the flow injection analysis was applied to the enzyme-entrapped sensor on a chip for sensing glucose. The microelectrode arrays on a chip of 7×3.5 cm2 were fabricated by standard photolithographic and the [...]

Hyperhtermia effect of surface-modified magnetite nanoparticles in a microfluid system

Lin C.Y., Ho K.C., National Taiwan University, TW

Fe3O4 nanoparticles (NPs) was first synthesized via coprecipiatation. After synthesis and purification of the Fe3O4 NPs, poly(acrylic acid) (PAA) was coated on them at specified conditions. The coating process is not possible at pH higher [...]
