Abstract
A method for adjusting the operating point of an avalanche photodiode is provided, in which the supply voltage of the avalanche photodiode is changed gradually and the total noise and the amplifier noise of an amplifier connected to the avalanche photodiode are determined, wherein the supply voltage is kept constant after reaching a certain ratio between the total noise and the amplifier noise.
