Methodology for the Digital Calibration of Analog Circuits and Systems Using Sub-binary Radix DACs

Maher Kayal, Marc Pastre

This paper presents a methodology for digitally calibrating analog circuits and systems. Based on the detection of an imperfection by a simple comparator, a successive approximations algorithm tunes a compensation current. The latter is generated by a sub- ...

A parametric AC loss model of the ITER coils for control optimization

Luca Bottura

A recent study on AC loss calculation in different operating regimes of relevance for ITER plasma control has shown that AC loss calculations can be performed on a model with a level of complexity and completeness not achieved so far [L. Bottura, P Bruzzon ...

A Parallel Evolutionary Algorithm to Optimize Dynamic Memory Managers in Embedded Systems

David Atienza Alonso, José Luis Risco Martin

For the last 30 years, several dynamic memory managers (DMMs) have been proposed. Such DMMs include first fit, best fit, segregated fit and buddy systems. Since the performance, memory usage and energy consumption of each DMM differs, software engineers of ...

Controlled Resonant Circuit with Commutated Capacitors using Self-Switching Power Devices

Alfred Rufer, Daniel Siemaszko, Christian Rod

This paper presents a preliminary work on a resonant circuit, also called AC-dipole. The resonance frequency of the circuit is changed by the mean of a variable capacitor connecting an inductor. For this purpose, a bank of switched capacitors of different ...

Impact of Materials and Design on Solid Oxide Fuel Cell Stack Operation

Jan Van Herle, Stefan Diethelm, Arata Nakajo, Zacharie Wuillemin, Nordahl Autissier

Planar SOFC stack technology based on a unique concept (SOFConnex™) uses structured gas distribution layers between unprofiled metal sheet interconnects and thin Ni-YSZ anode supported electrolyte cells. The layers are flexible both in material and designa ...

Pico-Watt Source-Coupled Logic Circuits

Seyed Armin Tajalli, Yusuf Leblebici

This article explores the main tradeoffs in design of subthreshold source-couple logic (STSCL) circuits. It is shown analytically that the bias current of each STSCL gate can be reduced to few pico-amperes with a reliable logic operation. Measurements on d ...

Microsensor for in situ flow measurements in benthic boundary layers at submillimeter resolution with extremely slow flow

Alfred Johny Wüest, Bernhard Wehrli

The currents in the lowest few millimeters of the bottom boundary layer of lakes are highly important for the dissipation of kinetic energy and for chemical processes such as oxygen transfer into the sediment. So far, no high-resolution flow velocity profi ...

Anomalies on V-I characteristic of NbTi cable-in-conduit conductors

Pierluigi Bruzzone, Boris Stepanov

Two kinds of anomaly, observed in the Volt-Ampere Characteristic (VAC) of large NbTi cable-in-conduit conductors (CICC) are discussed. In one case, the wavy behavior of the VAC close to the current sharing range is explained with oscillations of the coolin ...
