Abstract
Introduction: Investigation of low-frequency (1/f) noise in GaN/AlGaN heterostructurefield-effect transistors (HFET) has currently attracted a lot of attention. This is due to ademonstrated potential of GaN HFETs for high-power density and high frequencyapplications [1-2], as well as due to unusual properties of the low-frequency noise inthese devices. The latter include large noise spectral density, several orders of magnitudedifferences in Hooge parameter values, large deviation of...
