Low-power clock distribution networks for 3-D ICs

Giovanni De Micheli, Vasileios Pavlidis, Somayyeh Rahimian Omam

Designing a low power clock network in synchronous circuits is an important task. This requirement is stricter for 3-D circuits due to the increased power densities. Resonant clock networks are considered efficient low-power alternatives to conventional cl ...

Modeling of Printed Spiral Inductors for Remote Powering of Implantable Biosensors

Giovanni De Micheli, Sandro Carrara, Jacopo Olivo

Fully implantable biosensors require small size to be minimally invasive. To avoid embedded batteries, power can be supplied by means of printed spiral inductors located on the skin, close to the implanted devices. Reliable models are required to optimize ...

Direct two-dimensional measurements of the eld-aligned current associated with plasma blobs

Ambrogio Fasoli, Ivo Furno, Christian Gabriel Theiler, Nicola Vianello

In simple magnetized toroidal plasmas, field-aligned blobs originate from ideal interchange waves and propagate radially outward under the effect of

\grad B

and curvature induced

E \times B

drifts. We report on the first experimental two-dimensional me ...

Energy alignment and surface dipoles of rylene dyes adsorbed to TiO2 nanoparticles

Ulf Anders Hagfeldt

The energy loss in dye-sensitized solar cells calcd. from the energy difference between the lowest electronic transition of the dye and the obtained open-circuit voltage is often 1 eV or even more. To minimize this loss, it is important to accurately det. ...

Reversible DC/DC Converter as interface between Low and Medium Voltage DC Networks

Alfred Rufer, Stephan Kenzelmann, Carlo Arrioja

This paper introduces an isolated reversible DC/DC converter with a particular topology, which benefits from both the Neutral Point Clamped (NPC) structure and the series-parallel connection of converters. The key property of the proposed topology is the o ...

Understanding and taming plasma blobs in toroidal magnetized plasmas

Ivo Furno

Intermittent blobs, which propagate across a confining magnetic fields, are universally observed in natural and laboratory plasmas. In fusion plasmas, cross-field transport of particles and energy are associated, at least in part, with the propagation of b ...

Blob current structures in TORPEX plasmas: experimental measurements and numerical simulations

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Nicola Vianello, Davoud Iraji, Diane Virginie Marie Lançon

In the simple magnetized torus TORPEX, field-aligned blobs originate from ideal interchange waves and propagate radially outward due to del B and curvature induced drifts. Time-resolved two-dimensional measurements of the field-aligned current density J(pa ...

A Multiband Concurrent Sampling based RF Front End for Biotelemetry Applications

Christian Enz, Aravind Prasad Heragu Singaiyengar

A sub-sampling based multiband RF front end suitable for medical telemetry applications is presented. Using a single inductor and a single sampling frequency it is shown how to downconvert concurrently Bluetooth LE and MICS band signals to baseband with re ...

Very high-speed slotless permanent-magnet motors

Pierre-Daniel Pfister

The development of very high-speed motors has evolved fascinatingly in the last few years. Due to their speed, their low weight and their high power density, the need for such motors has recently increased for various different applications. Among them, su ...
