A 1.25 Gbps burst-mode receiver IC with extended dynamic range

A 1.25 Gbps burst-mode optical receiver for Ethernet passive optical networks is realized in a 0.35 /spl mu/m SiGe BiCMOS process. With dual-TIA topology, the sensitivity and overload of the receiver can be optimized independently. The measured results show a dynamic range of -28.4 dBm to -1 dBm and settling time less than 50 ns.
