  • Abstract
    It is shown that device self-heating effects introduce a significant error in the determination of emitter resistance in AlGaAs-GaAs HBTs by the common technique of extrapolating 1/gm against 1/lc (where gm is the observed device transconductance). An approximate expression for the error is given, and an improved technique for Re extraction is presented
