Claim 0:
1. A sensor device comprising:
a silicon substrate having an active surface,
a first sensing area disposed near a first edge of said active surface of said silicon substrate, said first sensing area comprising at least one first magnetic sensing element,
a second sensing area disposed near a second edge of said active surface of said silicon substrate, said second edge being substantially opposite to said first edge, said second sensing area comprising at least one second magnetic sensing element,
a processing circuit disposed in said silicon substrate and electrically connected with said first and said second sensing area and arranged to derive a first signal from said at least one first magnetic sensing element of said first sensing area, to derive a second signal from said at least one second magnetic sensing element of said second sensing area and to compute a difference between said first and said second signal;
wherein a distance between said first edge and a most nearby edge of a first magnetic sensing element of said first sensing area is less that 15% of a distance between said first edge and said second edge substantially opposite to said first edge, such that the sensor device is configured for a higher sensitivity.
