An automatic threshold control device for a burst mode optical receiver is disclosed. The receiver includes a converter that converts a burst mode signal into a voltage signal and an automatic gain controller for automatically controlling a gain of the converter, independently generating a reset signal and applying it to the automatic threshold control device. The automatic threshold control device is adapted to detect a voltage level of an output signal from the converter. The device includes a peak detector that detects a peak level of the output signal from the converter in response to the reset signal, a bottom level detector that detects a bottom level of the output signal from the converter in response to the reset signal, a pair of resistors having their one sides connected respectively to the peak detector and bottom level detector and their other sides connected to each other, the resistors generating a reference voltage on the basis of voltages of the peak level and bottom level, and a capacitor for storing the reference voltage.
