摘要

A model for soft breakdown effects in InP/ In GaAs-based single HBT's isdeveloped. The effects of large-signal excitation on the operational characteristics of optoelectronic preamplifiers, 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 for
