Abstract

A capacitive sensor detects an object, in particular detects a collision in the case of a movable vehicle part. The sensor has an electrode arrangement which contains at least one sensor electrode. The sensor also has an evaluation circuit which is connected downstream of the sensor electrode and is intended to process a reception signal generated in the sensor electrode. In this case, the evaluation circuit contains a transimpedance amplifier which has a device for compensating for the frequency response.
