1 Gbit/s CMOS photoreceiver with integrated detectoroperating at 850 nm

Abstract

A fully integrated single-beam optical receiver is realised in a production 0.35 µm CMOS process, which operates at 850 nm to 1 Gbit/s. The receiver integrates a photodiode, preamplifier, digital logic, and an off-chip driver. Pre-amplifier dissipation is < 1.5 mW at 2.3 V, with an average optical power of –6.3 dBm required for 1 Gbit/s operation. Such a compact optical receiver may be of interest for short distance optical interconnects or local area networks.
