The chopped Double Hall Switch comprises two Hall probes, bias generator,
compensation circuits, oscillator, and output transistors.
The bias generator provides currents for the Hall probes and the active circuits.
Compensation circuits stabilize the temperature behavior and reduce technology variations.
The Active Error Compensation rejects offsets in signal stages and the influence of
mechanical stress to the Hall probes caused by molding and soldering processes and
other thermal stresses in the package. This chopper technique together with the threshold
generator and the comparator ensures high accurate magnetic switching points.
