✦ Synopsis
A model for soft breakdown effects in InP/InGaAs-based single HBTs i s developed. The effects of large-signal excitation on the operational characteristics of optoelectronic preamplijiers, such as the transducer and transimpedance gain of individual transistors, are addressed. These effects depend on optoelectronic integrated-circuit (OEIC) design and are associated with self-bias variations due to input power levels. Cascode designs are relatively immune to these effects, whereas basic coupled
amplifiers are more sensitive (9-dB R 1)s. 3-dB R transimpedance reduction) for the same input power increase from -35 to -5 dBm.
