Abstract

In this work we present a high-speed optical receiver with external large-area photodiode. The optical receiver is realized in 0.35µm SiGe BiCMOS technology. The input circuit is a two-transistor transimpedance amplifier using an common-emitter and an emitter-follower configuration. An external silicon PIN photodiode of a squared area of 0.25mm2 with a rise time of 0.4ns at 850nm light is used. The POF-receiver offers quick response for 1.25Gbps optical wire-line access networks. In addition a high sensitivity is also required, where the receiver presented reaches a sensitivity of -26dBm at the optical input using low-cost silicon-based material only.
