Abstract
An electronic arrangement includes a first bias terminal, a ground terminal, a photodiode including an anode terminal and a cathode terminal, and a transimpedance amplifier including an operational amplifier. The electronic arrangement is selectively switchable to a photocurrent measurement mode and a temperature measurement mode. In the photocurrent measurement mode: the anode terminal is connected to a first input of the operational amplifier; the cathode terminal is connected to a second input of the operational amplifier; and the first bias terminal is connected to the first input of the operational amplifier and the anode terminal. In the temperature measurement mode: the anode terminal is connected to the ground terminal; the cathode terminal is connected to the second input of the operational amplifier; and the first bias terminal is connected to the first input of the operational amplifier and disconnected from the anode terminal.
