Abstract :
A large-signal model suitable for InP/InGaAs HBTs was developed. Breakdown effects have been incorporated into the Gummel-Poon formulation. The new model was validated by comparisons with on-wafer power measurements. The characteristics of two transimpedance amplifiers of different design were studied using the large-signal models developed for InP/InGaAs HBTs. The analysis showed that circuit characteristics can be modified under large-signal operation. Transimpedance degradation and pronounced self-bias can, for example, take place and these depend on the type of OEIC. Large-signal modeling should therefore be considered for accurate OEIC design
