| 英文摘要 | Methods and system are provided for automatic power control of a laser diode, e.g., in a laser driver. In accordance with an embodiment of the present invention, a power controller includes a detector circuit (107) adapted to detect the output (104a) of the laser diode and to produce a measured output therefrom. A comparator (130) compares a desired output to the measured output, and produces an error signal therefrom. The error signal is provided to an integrator circuit (131) that produces an integrated error signal. At least one digital-to-analog converter (DAC) (142) uses the integrated error signal to produce a current drive signal that drives the laser diode (102). |
