Advanced EMI input filtering for an industrial power supply with a resonant stage

Different EMI filters have been designed for an industrial power electronic converter system and a study on the performance of these different input filter topologies has been performed. Based on one filter topology a study on the influence of the orientat ...

CAD tools for fast analysis of parasitic coupling and mismatch effects in switched-capacitor circuits

Maher Kayal, Sylvain Maréchal, François Krummenacher

This paper presents a switched-capacitor simulator, optimized for fast computations. Two CAD tools are implemented in order to perform Monte-Carlo simulations, to identify sensitive parasitic coupling prior to layout and to rapidly verify parasitic couplin ...

MAGY: an innovative high voltage - low current power supply for gyrotron

Damien Fasel, Ugo Siravo, Albert Perez, Mauro Carpita

From the electrical point of view, the body and the anode of high power gyrotrons behave as capacitive loads. A highly dynamic power supply is, therefore, hard to achieve. The MAGY concept (Modulator for the Anode of a triode type GYrotron) embodies an inn ...

Deciphering surface enhanced Raman scattering activity of gold nanoworms through optical correlations

Vasiliki Tileli

Surface enhanced Raman scattering (SERS) "hot spots" are the regions where the electromagnetic field is significantly enhanced, resulting in much greater SERS activity than other areas. Therefore, the engineering and characterization of "hot spots" have at ...

Tunable band-stop filter based on single RF MEMS capacitive shunt switch with meander arm inductance

Mihai Adrian Ionescu, Catherine Dehollain, Montserrat Fernandez-Bolanos Badia

This paper presents a novel high-frequency tunable band-stop filter concept based on a single MEMS capacitive shunt device which uses meander arm anchoring inductors and with a total size of 300 × 600 μm. Tuning ranges of the central frequency in the order ...

Capacitively coupled contactless conductivity detection with dual top-bottom cell configuration for microchip electrophoresis

Nico de Rooij

An optimized capacitively coupled contactless conductivity detector for microchip electophoresis is presented. The detector consists of a pair of top bottom excitation electrodes and a pair of pickup electrodes disposed onto a very thin plastic microfluidi ...

Capacitive flexible force sensor

Martinus Gijs, Jagoda Anna Dobrzynska

We have realized a flexible force sensor, composed of four redundant capacitors, the operation of which is based on the measurement of a load-induced capacitance change. We use polyimide both as flexible substrate and as elastic dielectric between two leve ...

Self-aligned nanolithography by selective polymer dissolution

Francesco Stellacci

We report a novel approach to the fabrication of self-aligned nanoscale trench structures in a thin polymer layer covering on conductive materials. By passing AC current through a polymer-coated nanowire in the presence of an appropriate solvent, a self-al ...

High coupling materials for thin film bulk acoustic wave resonators

Janine Conde

Radio frequency (RF) filters based on bulk acoustic wave resonances in piezoelectric thin films have become indispensable components in mobile communications. The currently used material, AlN, exhibits many excellent properties for this purpose. However, i ...

Tunable band-stop filter based on single RF MEMS capacitive shunt switch with meander arm inductance

Mihai Adrian Ionescu, Catherine Dehollain, Montserrat Fernandez-Bolanos Badia

This paper presents a novel high-frequency filter concept based on a single MEMS capacitive shunt structure using meander arm inductance. Tuning ranges of the central frequency in the order of 55% are experimentally demonstrated for filters operating betwe ...
