ABSTRACT:
Systems and methods for continuously compensating a modulation current of a laser. A temperature compensation circuit has circuitry with a positive temperature coefficient connected with circuitry having a negative temperature coefficient. The temperature compensation circuit generates a temperature dependent reference current that is mirrored to a gain circuit. The gain circuit provides variable gain. The gain circuit also provides inputs that can be set to select a particular gain. The output of the gain circuit, which changes as temperature affects the reference current, is used to compensate the modulation current of the laser.
