The present invention relates to a method for biasing a photodiode (1) with a bias voltage (UB) and to a photodiode bias circuit performing said method. The photodiode (1) is producing a photocurrent (IP). According to the invention the following steps are performed: Reading a measurand (U1) related to the photocurrent (IP). Comparing the measurand (U1) with a threshold (Uth). Giving the bias voltage (UB) a magnitude depending on whether the measurand (U1) is larger than the threshold (Uth) or smaller.
