Abstract
A method for sensing an angular orientation of a magnetic field includes providing a set of N≧2 Hall effect devices, each having a detection direction and including two pairs of connectors; providing at least one band pass filter having a fundamental frequency f=1/Tf; providing at least one current source for outputting an electrical current at its output; applying, during a first time period of a duration 0.5 Tf and in a specific sequence of the N Hall effect devices, to each of the N Hall effect devices a respective wiring scheme Wi+, during respective subsequent time periods of durations ti; and applying, during a second time period of a duration 0.5 Tf, subsequent to the first time period of a duration 0.5 Tf, and in the same specific sequence of the N Hall effect devices, to each of the N Hall effect devices a respective wiring scheme Wi−, during respective subsequent time periods of the same durations ti.
