Abstract

Commercial pseudomorphic AlGaAs/InGaAs HEMTs designed for low noise operation have demonstrated weak sensitivity to hot electron stress. We have investigated underlying physical mechanisms by LF channel noise analysis and Drain Current Transient Spectroscopy (DCTS). A link has been established between the enhancement due to hot electron stress of the hole current collected by the gate and the modulation of electron trap effective density located beneath the gate.
