On the effect of linear feedback and parametric pumping on a resonator's frequency stability

Resonant sensors based on micro- and nano-electro mechanical systems (M/NEMS) are ubiquitous in many sensing applications due to their outstanding performance capabilities, which are directly proportional to the quality factor (Q) of the devices. We addres ...

Enhanced-performance integrated Resonant Switched-Capacitor and Buck DC-DC converters for application in extreme radiation and magnetic field environments

Giacomo Ripamonti

DC-DC converters based on Application Specific Integrated Circuits (ASICs) have been developed in this doctoral work for the High-Luminosity Large Hadron Collider (HL-LHC) experiments at CERN. They step down the voltage from a 2.5 V line and supply a load ...

Laser-Induced Transition between Nonlinear and Linear Resonant Behaviors of a Micromechanical Oscillator

Yves Bellouard, Tao Yang

We investigate both theoretically and experimentally a laser-based controlled tuning of the nonlinear behaviors of a single mechanical resonator. Thanks to localized three-dimensional modifications induced by femtosecond-laser irradiation, a Duffing-like o ...

T0003 / MilliNewton & CentoNewton force sensors / Deviation from ratiometric behaviour

Thomas Maeder

This document concerns the deviation of the output of MilliNewton and CentoNewton force sensors from ideal ratiometric behaviour. These sensors nominally operate from a single +5 V supply voltage and, as they have no voltage regulator, their output respons ...

On-Chip Digital Background Calibration of Pipelined Analog-to-Digital Converters using Digital Assistance to support Nonlinear Residue Amplification

Thomas Liechti

This thesis describes a novel digital background calibration scheme for pipelined ADCs with nonlinear interstage gain. Errors caused by the nonlinear gains are corrected in real-time by adaptively post-processing the digital stage outputs. The goal of this ...

Inkjet Printing of Silver on Flexible Substrates for Sensing Applications

Nico de Rooij, Danick Briand, Jérôme Courbat, Francisco Molina Lopez

We report on the fabrication of a low cost sensing platform which includes printed / electroplated resistive thermometers and capacitive-based humidity sensors working at ultra low power consumption. Both types of devices were integrated on the same polyme ...

Modal behavior of a reduced scale pump-turbine impeller. Part 1: Experiments

François Avellan, Mohamed Farhat, Eduard Egusquiza

An experimental investigation has been carried out to quantify the effects of surrounding fluid on the modal behavior of a reduced scale pump-turbine impeller. The modal properties of the fluid-structure system have been obtained by Experimental Modal Anal ...

AIN Thin Film Structures for High-Q Resonators

Alvaro Artieda

The development of wireless and mobile communication in the last decade led to the elaboration of new components based on thin films with continually increasing performance and reduced fabrication cost. A fundamental element for mobile communication is the ...

Hydrodynamic Damping Identification from an Impulse Response of a Vibrating Blade

François Avellan, Mohamed Farhat, Steven Roth, Martin Calmon

In the present study, the identification of hydrodynamic damping is investigated in the case of 2D blade placed in the test section of the EPFL High Speed Cavitation Tunnel. A non intrusive technique, based on a spark generated bubble, is used to generate ...

The dynamical response properties of neocortical neurons to temporally modulated noisy inputs in vitro

Michele Giugliano

Cortical neurons are often classified by current-frequency relationship. Such a static description is inadequate to interpret neuronal responses to time-varying stimuli. Theoretical studies suggested that single-cell dynamical response properties are neces ...
