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 ...

The Common Cross-Connected Stage for the 5L ANPC Medium Voltage Multilevel Inverter

Alfred Rufer

Rising interest in multilevel applications has triggered new research activities. This paper proposes a novel multilevel power electronics building block (PEBB) for the five-level active neutral point clamped (ANPC) multilevel voltage source inverter. The ...

Direct Observation of Capacitor Switching Using Planar Electrodes

Alexander Tagantsev

Ferroelectric polarization switching in epitaxial (110) BiFeO3 films is studied using piezoresponse force microscopy of a model in-plane capacitor structure. The electrode orientation is chosen such that only two active domain variants exist. Studies of th ...

Annealing effects on electrical properties and defects of CaCu_{3}Ti_{4}O_{12} thin films deposited by pulsed laser deposition

Paul Muralt

A systematic study was carried out to assess property changes in CaCu3Ti4O12 thin films upon annealing in air in order to evaluate the impact of oxygen vacancies on their colossal dielectric constant behavior. Highly preferentially oriented thin-film sampl ...

A theory of sound transmission through a clamped curved piezoelectric membrane connected to a negative capacitor

Hervé Lissek, Tomas Sluka, Pavel Mokry

An analytical calculation of the acoustic transmission loss of sound propagating through a thin cylindrically curved piezoelectric membrane, which is rigidly clamped at its straight ends, is presented. The membrane is placed inside an acoustic tube and con ...

Control of a multilevel modular DC/DC converter for mobile applications

Alfred Rufer, Daniel Montesinos Miracle

This paper presents the control design of a multilevel modular DC/DC converter for regenerative braking systems in mobile applications. The proposed control scheme is able to control the energy flow between supercapacitors and the DC link and equalizing th ...

Offset compensation based on distributed Hall system architecture

Radivoje Popovic, Pavel Kejik

Integrated Hall devices have the great advantage, over other magnetic sensors, that they can be fully fabricated by a standard CMOS process. However they are known to have a relatively large offset (i.e. residual voltage at zero magnetic field). Techniques ...

Metal-Ferroelectric-Metal-Oxide-Semiconductor Field Effect Transistor with Sub-60mV/decade Subthreshold Swing and Internal Voltage Amplification

Mihai Adrian Ionescu, Giovanni Antonio Salvatore, Alexandru Rusu

This work reports the first complete experimental demonstration and investigation of subthreshold swing, SS, smaller than 60 mV/decade, at room temperature, due to internal voltage amplification in FETs with a Metal-Ferroelectric-Metal-Oxide gate stack. Th ...

Energy Storage System With Supercapacitor for an Innovative Subway

Philippe Barrade

In this paper, a new energy storage system (ESS) is developed for an innovative subway without supply rail between two stations. The ESS is composed of a supercapacitor bank and a braking resistor. An inversion-based control of the ESS is deduced from the ...
