BURST-MODE OPTICAL RECEIVER AND POWER LEVEL DETECTOR IN AN FOR RECEIVING BURST-MODE SIGNAL THEREFOR

摘要

the present invention in which the current signal output from the optical detector to convert the voltage signal to a pre-amplifier which comprises an optical In the LOS (Loss Of Singnal) and signal level detection unit for outputting a reset signal from the output from the preamplifier in the receiver, and the output is the input capacitor from the pre-amplifier, the emitter and collector to the output of the preamplifier a third transistor having a respective connection with the respective base and collector and a first and a second transistor which are connected to each other, a collector connected to the collector of the first transistor and the emitter connected to the collector of the second transistor and the third consists of a pair of resistors respectively connected to the emitter and collector of the transistor, characterized in that it comprises a common emitter circuit which is capable of detecting the amplitude of the input signal from the collector of the third transistor.
