Abstract
A burst-mode optical receiver of a differential-output structure is disclosed. The burst-mode optical receiver includes a trans-impedance amplifier for converting currents indicating the burst-mode signals into voltage signals, a bottom-level detector for detecting the bottom level of signals outputted from the trans-impedance amplifier, an automatic gain controller for automatically adjusting a gain to prevent the output waveforms of the tran-simpedance amplifier from being distorted after receiving the bottom-level signals detected by the bottom-level detector, a top-level detector for detecting the top level of signals outputted from the trans-impedance amplifier, a pair of resistors for generating a signal-reference voltage from the bottom- and top-level voltages, one side of each resistor being connected to the bottom- and top-level detectors, respectively, and the other sides of each resistor being connected to each other, and a differential buffer for receiving outputs from the trans-impedance amplifier and the signal-reference voltage from the pair of resistors and for eliminating the offsets generated from the bottom- and top-level detectors in order to supply two differential outputs.
