The method for sensing an angular orientation of a magnetic field includes a) providing a set of N≧2 Hall effect devices, each having a detection direction and comprising two pairs of connectors; b) providing at least one band pass filter having a fundamental frequency f=1/Tf; c) providing at least one current source for outputting an electrical current at its output; d1) applying, during a first time period of a duration 0.5 Tf and in a specific sequence of said N Hall effect devices, to each of said N Hall effect devices a respective wiring scheme Wi+, during respective subsequent time periods of durations ti; and d2) applying, during a second time period of a duration 0.5 Tf, subsequent to said first time period of a duration 0.5 Tf, and in the same specific sequence of said N Hall effect devices, to each of said N Hall effect devices a respective wiring scheme Wi−, during respective subsequent time periods of the same durations ti. |
