In this manuscript reliability issues in GaAs pHEMTs are empirically investigated. Starting from typical reliability approaches where the average value of the gate current is dealt with, we show that an exhaustive information for reliability analysis can be obtained only by looking at the gate current dynamic behaviour. Different experimental examples are provided in order to demonstrate the validity of the proposed considerations.

Abstract
In this manuscript reliability issues in GaAs pHEMTs are empirically investigated. Starting from typical reliability approaches where the average value of the gate current is dealt with, we show that an exhaustive information for reliability analysis can be obtained only by looking at the gate current dynamic behaviour. Different experimental examples are provided in order to demonstrate the validity of the proposed considerations.File in questo prodotto:
