Abstract: An apparatus for reading out a time-continuous sensor output signal of a sensor, modulated with a fundamental frequency, has a loop filter, a sample-quantizer and a feedback circuit. The loop filter, filters the sensor output signal to provide a filtered sensor output signal in which frequency proportions present in a frequency range Δf with respect to the fundamental frequency f0 are amplified. The sample-quantizer samples and quantizes the filtered sensor output signal to provide a time-discrete, quantized sensor output signal. The feedback circuit feeds a feedback signal based on the time-discrete, quantizes sensor output signal back to the loop filter and provides a readout signal, wherein the readout signal corresponds to the time-discrete, quantized sensor output signal or the time-discrete, quantized sensor output signal demodulated with respect to the fundamental frequency f0.
