Abstract
A sensor arrangement () comprises an amplifier () having a signal input () to receive an input signal (SIN) and a signal output () to provide an amplified sensor signal (SOUT) that is an inverted signal with respect to the input signal (SIN). Furthermore, the sensor arrangement () comprises a feedback path connecting the signal output () to the gnal input (), wherein the feedback path comprises a series connection of a capacitive sensor () and a feedback capacitor (). A voltage source arrangement () of the sensor arrangement () is connected to a feedback node () between the capacitive sensor () and the feedback capacitor ().
