摘要： In various embodiments, a measuring arrangement is provided. The measuring arrangement may include a micromechanical sensor including a capacitor, a bridge circuit including a plurality of capacitors, at least one capacitor of which is the capacitor of the micromechanical sensor, an amplifier coupled, on the input side, to an output of the bridge circuit, a DC voltage source configured to provide an electrical DC voltage, a chopper including at least one first charge store and a switch structure, The switch structure is configured to couple the first charge store alternately to the DC voltage and the bridge circuit for the purpose of coupling an electrical mixed voltage into the bridge circuit.
