We present a compact experimental technique for the extraction of all parasitic series resistances of bipolar transistor, which requires only few DC measurements and no special device structure. The method is based upon the fact that, due to impact ionization within the base-collector space-charge region, at a certain collector-base voltage the base current and therefore the voltage drop on the parasitic base resistance are reduced to zero.

Abstract
We present a compact experimental technique for the extraction of all parasitic series resistances of bipolar transistor, which requires only few DC measurements and no special device structure. The method is based upon the fact that, due to impact ionization within the base-collector space-charge region, at a certain collector-base voltage the base current and therefore the voltage drop on the parasitic base resistance are reduced to zero.File in questo prodotto:
