Abstract
A circuit arrangement, an electrochemical sensor, a sensor arrangement, and a method for processing a current signal provided by a sensor electrode are disclosed. The circuit arrangement includes a sensor electrode, a first circuit unit, electrically coupled to the sensor electrode and a second circuit unit, including a first capacitor, whereby the first circuit arrangement is embodied to hold the electrical potential of the sensor electrode in a given first reference range about a set electrical potential and, when the sensor electrode potential falls outside the first reference range, the first capacitor and the sensor electrode are coupled such that a matching of the electrical potentials is possible. The second circuit unit is embodied such that, when the electrical potential of the first capacitor falls outside a second reference range, this event is detected and the first capacitor brought to a first electrical reference potential.
