A 10-Gb/s burst-mode limiting amplifier using a two-stage active feedback circuit

摘要

A 10.3125-Gb/s burst-mode limiting amplifier (LIA) for 10G-EPON systems has been developed. The LIA is composed of two-stage amplifiers with active feedback that provides automatic voltage offset cancellation (AOC) in 200 ns for both 20- and 200-mVpp input. The AOC time of 200 ns is 75% faster than the maximum settling time of 800 ns in 10G-EPON specifications. The LIA with a receiver optical subassembly has a sensitivity of −29 dBm and a dynamic range of 23 dB at BER of 10−3.
