Abstract:
1. A circuit for a magnetic-field sensor that includes a first detection structure configured to detect a first directional component of an external magnetic field and a second detection structure configured to detect a second directional component of said external magnetic field, the circuit comprising: a biasing circuit configured to electrically supply said first detection structure during a first biasing time interval and to electrically supply said second detection structure during a second biasing time interval, the first and second bias time intervals being at least partially distinct from one another in that the bias circuit is configured to electrically supply said first detection structure without electrically supplying said second detection structure during at least a portion of the first bias time interval and is configured to electrically supply said second detection structure without electrically supplying said first detection structure during at least a portion of the second bias time interval, wherein said biasing circuit is configured to electrically supply a third detection structure of the magnetic field sensor during a third biasing time interval to enable the third detection structure to detect a third directional component of the external magnetic field, the first, second, and third biasing time intervals being at least partially distinct from one another.
