Abstract
A device for detecting an approach or a touch related to at least one sensor element, in particular in an electrical appliance, the device comprising an input side and an output side, between which a first signal path with a first input and a first output and a second signal path with a second input and a second output are arranged, wherein the first signal path comprises a delay device with a delay, the delay device configured to delay a digital first input signal at the first input into a digital first output signal at the first output, wherein the delay is dependent on a capacitance value resulting from the approach or the touch related to the sensor element, and wherein the second signal path comprises an XOR-element, which is configured to generate an edge in a digital second output signal at the second output, when the digital first output signal outputted by the delay device exhibits an edge.
