A photosensor arrangement may include an amplifier configured to receive charge from a photosensor device at a first input, and a second input configured to receive a first reference voltage. The amplifier may provide an output voltage on an output. A comparator has a first input at the output voltage, a second input at the first reference voltage and is configured to provide a compare output. A capacitor is configured to have a first plate coupled to the output of the amplifier and a second plate coupled to the first input of the comparator.
