A Hall sensor analog front end for current measurement with continuous gain calibration

This paper presents a new technique for continuously calibrating the sensitivity of a current measurement microsystem based on a Hall magnetic field sensor. An integrated reference coil generates a magnetic field for calibration. Using a variant of the cho ...

Circular Hall transducer for angular position sensing

Radivoje Popovic, Pavel Kejik

We developed a new integrated magnetic sensor based on the Hall effect, suitable for contactless 360 degrees absolute angle encoding. The sensing device consists of a narrow n-well ring with a chain of 64 contacts equally distributed along the ring. It is ...

Source–Drain Partitioning in MOSFET

Christian Enz, Jean-Michel Sallese, Ananda Sankar Roy

The Ward-Dutton (WD) partitioning scheme [IEEE Trans. Electron Devices, vol. ED-27, p. 1571, Aug. 1980] is used extensively to develop transient and high-frequency advanced compact models for MOSFET devices. Recently, it has been shown that WD partitioning ...

Bias Field Correction in Magnetic Resonance Images of a Rat Brain

Jean-Philippe Thiran, Rolf Gruetter, Meritxell Bach Cuadra, Nathalie Just, Xavier Pena Pina

Magnetic Resonance Imaging (MRI) is nowadays a widely used medical tool, as it is a non-invasive and non-harmful way to study inner soft tissues. One of the characteristics of this method is the bias field, also called Intensity In-homogeneity (IIH), which ...

Transistors organiques ultraminces à base de pentacène

Adrian von Mühlenen

The goal of this thesis is to contribute to the understanding of charge transport in organic field-effect transistors (OFETs) made of pentacene. Organic thin-film transistors (OTFTs) with active layers thicknesses of 5, 10, 20, and 100 nm were fabricated i ...

Automatic calibration of Hall sensor microsystems

Maher Kayal, Marc Pastre

In many applications, a Hall element is used for contact-less measurement such as linear and angular positions, electrical current, power and energy, etc. The Hall element fabricated by means of CMOS technology features mediocre characteristics [R.S. Popov ...

Hall sensor and method of operating a Hall sensor

Giovanni Boero, Radivoje Popovic, Pavel Kejik, Predrag Drljaca

A Hall sensor comprises a Hall element (1; 30; 31; 60) and an amplifier (2; 32; 33). The Hall element is placed inside the amplifier so that the current flowing through the Hall element also flows through the transistors of an amplifier stage of the amplif ...
