Analysis of operation of fast peak detectors in burst-mode fibre optic receivers

181-188

In the paper, the analysis of operation of fast peak detectors is presented. It is assumed that the signal driving the detector is composed of short pulses with amplitude in the order of a few mV. Such detectors are used in the fibre optic burst-mode networks, where digital data is conveyed in the form of packets, which differ in amplitude substantially. Peak detectors are used there to determine proper threshold voltage that is necessary to perform data detection in each packet. The paper is focused mostly on the effects occurring in the peak detectors with transconductance amplifier in the feedback loop, resulting from amplifier bandwidth limitation and presence of stray capacitances.
