Abstract

A circuit arrangement for an optical monitoring system comprises a driver circuit which is configured to generate at least one driving signal for driving the light source. A detector terminal is arranged for receiving a detector current from an optical detector. A gain stage is connected at its input side to the driver circuit for receiving the driving signal and generates a noise signal depending on the driving signal. A processing unit is configured to generate an output signal depending on the detector current and the noise signal.
