A simple PIN photodiode-bipolar transistor (PIN-BJT), direct-coupled, transimpedance, optical preamplifier suitable for fabrication in monolithic IC form is described. The preamplifier basically consists of a common-collector, commonemitter configuration with shunt feedback. Measurements indicate that the receiver is capable of a sensitivity of −35.8 dBm at 140 Mbit/s for an error rate of 10-9.
