摘要：
A light transmitter and an auto-control circuit thereof are provided. The circuit includes a driving module and a feedback module. The driving module is coupled to the feedback module and a load. The driving module provides a driving current for driving the load. The feedback module provides a bias signal to the driving module according to the change of the temperature, for adjusting the driving current and stabilizing an output power.
