1. A system comprising:
a photodetector, wherein the photodetector is configured to provide a photodetector signal;
an amplifier connected to the photodetector, wherein, in response to receiving a bias signal, the amplifier is configured to amplify the photodetector signal;
a channel selector, wherein the channel selector is configured to provide the bias signal to the amplifier; and
a diode and a resistor coupled in parallel between an input of the amplifier and the channel selector.
