A novel planar magnetic sensor based on orthogonal fluxgate principle

Radivoje Popovic, Pavel Kejik, Franck Vincent, Ozge Zorlu

In this paper, we present a new planar fluxgate magnetometer structure. The sensor has the orthogonal fluxgate configuration which makes the detection part independent of the excitation mechanism. The sensor consists of a ferromagnetic cylindrical core cov ...

Offset Compensation Based on Distributed Hall Cell Architecture

Pierre-François Thibault Bourdelle, Pierre-André Farine, Pavel Kejik

A new offset reduction strategy for CMOS Hall devices is proposed. The novelty is to fragment the Hall device into multiple Hall blocks, distributed over the silicon area and easy to interconnect. The suitable number of Hall blocks and the bias current lev ...
