ABSTRACT:
The invention relates to a circuit configuration for compensating for the changes in a transfer ratio of a magnetic field sensor arrangement. According to one embodiment of the invention, a control loop for effecting this compensation is provided in the form of an integrated circuit whereby the change in transfer ratio is compensated by means of a control signal variation. This circuit configuration includes a series configuration of an A/D converter, a digital controller and a D/A converter exhibiting high precision and high control speed. A control that is significantly more precise and faster than that of the prior art is achieved by virtue of the fact that only a variable portion of regulating variables is fed through the digital controller after which a constant portion of regulating variables for the actual regulating variable used for compensation is added.
