1. A digital automatic gain control method in a burst mode optical receiver having an optical detector and a transimpedance amplifier for converting an output current signal of the optical detector into a voltage signal, the digital automatic gain control method comprising:

  • detecting a bottom holding level of the outputted voltage signal when a burst begins;

    generating a reset signal using a reference voltage generated according to an output signal of the transimpedance amplifier;

    comparing the detected bottom holding level with an input signal; and

    controlling a gain of the transimpedance amplifier by generating an automatic gain control signal according to the comparison result.
