A new extraction technique for the series resistances of semiconductor devices based on the intrinsic properties of bias-dependent y-parameters [bipolar transistor examples]

This paper presents an approach for the extraction of the series parasitics of semiconductor devices. The approach is based on the inherently different bias dependent behavior of y-parameters for a device with series parasitics compared to a device without series parasitics. The principles of this new method are verified analytically as well in simulations using the ADS Gummel-Poon model. In conclusion we have applied the proposed extraction method on measured data of DIMES-03 bipolar transistors of different sizes.
