On-Chip High-Voltage Sensors Based on Trap-Assisted 2DEG Channel Control

Elison de Nazareth Matioli, Armin Jafari

In this work, we present a new device concept for compact high-voltage sensing with high-impedance input port, consisting of an AlGaN/GaN high-electron-mobility channel controlled by trapped carriers generated by a metallic electrode. The high-voltage appl ...

Multilevel two quadrant DC/DC converter for regenerative braking in mobile applications

Alfred Rufer, Daniel Montesinos Miracle

In this paper different cascaded and multilevel topologies are compared for regenerative braking systems using supercapacitors (SC). It shows that the multilevel buck derived topology can beneficiate from both reduced voltage across the inductor and increa ...

Recombination coefficients of GaN-based laser diodes

Nicolas Grandjean, Jean-François Carlin, Julien Dorsaz, Luca Alex Milo Sulmoni

We measure the charge carrier recombination coefficients of InGaN quantum wells by analyzing the dynamical properties of (Al,In)GaN laser diodes emitting in the violet spectral range. Relaxation oscillations and turn-on delays are fitted to a rate equation ...

Design of an integrated low-noise read-out system for DNA capacitive sensors

Sandro Carrara, Daniela De Venuto

This paper presents an electronic system for a fast DNA label-less detection. The sensitivity of the capacitive sensor in use is improved by depositing an insulating self-assembled monolayer (SAM) over the golden electrodes. The capacitance shift due to th ...

Gel-free IEF in a membrane-sealed multicompartment cell for proteome prefractionation

Hubert Girault, Hoang-Trang Lam

A minidevice for performing gel-free proteome prefractionation via conventional IEF in soluble carrier ampholyte buffers is reported here. It consists of a compact block of poly-oxymethylene in which eight samples and two electrode chambers are machined. E ...
