The kink effect is a detrimental phenomenon for the performance of III-V compound semiconductor FETs, resulting in output-conductance increase, transconductance compression, and dispersion between DC and RF characteristics. Although several papers have been dedicated to it, the physical origin of this effect is still a debated issue [1-4]. The aim of this work is to provide insight about the physical origin and the dynamic behavior of the kink in AlGaAs/GaAs HFETs.

Abstract
The kink effect is a detrimental phenomenon for the performance of III-V compound semiconductor FETs, resulting in output-conductance increase, transconductance compression, and dispersion between DC and RF characteristics. Although several papers have been dedicated to it, the physical origin of this effect is still a debated issue [1-4]. The aim of this work is to provide insight about the physical origin and the dynamic behavior of the kink in AlGaAs/GaAs HFETs.File in questo prodotto:
