ABSTRACT:
A circuit configuration for processing a signal of a sensor includes an amplifier for amplifying the signal of the sensor. This signal has switch-over points between different signal states. The circuit configuration is constructed in such a manner that the amplifier and the sensor operate continuously in a chopper mode. Furthermore, a control loop is provided for determining offset components in the signal of the sensor and for removing the offset components from the signal of the sensor.
