Implementation Guidelines for a Real-Time Fault Location System in Electrical Power Networks

Maher Kayal, François Krummenacher, François Pierre Gaugaz

This paper presents constraints involved in the microelectronic implementation of a transmission line model based on transconductor-capacitor (gm-C) topologies. The presented line model, based on the discretization of a transmission line into a finite numb ...

Power and Area Efficient MOSFET-C Filter for Very Low Frequency Applications

Seyed Armin Tajalli, Yusuf Leblebici

New circuit design techniques for implementing very high-valued resistors are presented, significantly improving power and area efficiency of analog front-end signal processing in ultra-low power (ULP) biomedical systems. Ranging in value from few hundreds ...

PZT thin film growth and chemical composition control on flat and novel three-dimensional micromachined structures for MEMS devices

Florian Calame

Piezoelectric micro-electro-mechanical systems (MEMS) are finding an increased interest for applications requiring high frequency operation and high mechanical quality. The aim of this work was to improve piezoelectric MEMS along two main research directio ...

Development of low-temperature thick-film materials for piezoresistive sensors

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot

Thick-film materials are very advantageous for piezoresistive pressure and force sensors because of ease of processing, reliability and low cost. However, their applications are restricted because standard thick-film materials require processing temperatur ...

Size effect on permittivity in ferroelectric polydomain thin films

Nava Setter, Alexander Tagantsev, Pavel Mokry

The impact of electrode-adjacent passive layers on the small signal dielectric response of a ferroelectric film containing a 180degrees-domain pattern has been analyzed. It is shown that, for a realistic physical situation, the so-called "in-series capacit ...

Current capability and power density of supercapacitors: considerations on energy efficiency

Alfred Rufer, Philippe Barrade

Supercapacitors are components for energy storage. Due to their series resistors, the energy efficiency of supercapacitors can be low. In this paper, the unloading of supercapacitors with constant current and power are studied, to identify and take into ac ...

Considerations on the energy efficiency of a supercapacitive tank

Alfred Rufer, Philippe Barrade

Supercapacitors are electrochemical double layer capacitors, dedicated for the energ storage. Even if the energy density is still lower than that one of batteries, the supercapacitors are defined with a higher power density. The main advantage of that prop ...

Influence of texture on the switching behavior of Pb(Zr0.70Ti0.30)O-3 sol-gel derived thin films

Nava Setter

Rhombohedral Pb(Zr0.70Ti0.30)O-3 thin films of four different well-defined textures, namely, (100), (111), bimodal (110)/(111), and (100)/(111), were prepared by a sol-gel method. The films were characterized in terms of grain size, presence of second phas ...

Organization and expression of the pyruvate dehydrogenase complex genes of Escherichia coli K12

Stewart Cole

The organization and expression of the pyruvate dehydrogenase complex genes, aceE (E1), aceF (E2) and lpd (E3), were investigated using a series of λ transducing phages carrying different segments of the nadC-aroP-aceE-aceF-lpd region of the chromosome of ...
