Novel 1.25Gb/s CMOS burst mode optical receiver with automatically gain controllable preamplifier and high sensitive peak detector without external reset signal

Abstract

This paper introduces a novel feed-forward type burst mode optical receiver, which has automatically gain controllable preamplifier and high sensitive peak detector using a 0.18µm CMOS technology. The important feature of the receiver is that it operates with a reset signal that is self-generated inside the receiver not applied externally. The designed receiver can be used in the Ethernet PON (Passive Optical Network) system and has a sensitivity of -28dBm and a overload of -8dBm at 1.25Gb/s optical input signal.
