摘要

Current dispersion is an issue in AlGaN/GaN HEMTs. Different methods have been reported to investigate this phenomenon. This study reports an investigation of intrinsic components from small-signal model of AlGaN/GaN HEMTs right after off-state bias in linear and saturation regions in addition to drain-lag measurement. Different variations on the intrinsic components after off-state bias in linear and saturation regions were observed after switching from off-state bias. A significant current dispersion from drain-lag measurement is related to the increase in Rds and decrease in Cds extracted from small-signal model. However, less changes in Cgs and Cgd were observed.
