Abstract
In an embodiment a pixel arrangement includes at least one photodiode configured to convert electromagnetic radiation into a respective charge signal, a transfer gate between the photodiode and a capacitance for transferring the respective charge signal to the capacitance, a reset gate electrically coupled to the capacitance, the reset gate configured to reset the capacitance, an amplifier electrically connected to the capacitance and configured to generate, based on the respective charge signal and on a sensitivity mode, a respective amplified signal being a low sensitivity signal or a high sensitivity signal, respectively, wherein the low sensitivity signal and the high sensitivity signal are based on a common noise level, a first capacitor configured to store the high sensitivity signal, a second capacitor configured to store the low sensitivity signal, a first switch between an output terminal of the amplifier and the first capacitor and a second switch between the output terminal of the amplifier and the second capacitor.
