A 1.25 Gb/s high sensitive peak detector in optical burst-mode receiver using a 0.18 /spl mu/m CMOS technology

This paper introduces a novel peak detection in the burst-mode receiver considering the extinction ratio (6dB) of the received burst packet cells. The peak detector is designed using a 0.18 /spl mu/m CMOS technology and can be applied to the optical burst-mode receiver in an Ethernet PON system. By adopting this method, we can get the -29 dBm sensitivity and -8 dBm overload at 1.25 Gb/s.
