Extraction of bipolar SPICE Gummel-Poon parameters related to reverse Gummel (Ie and Ib vs. Vbc) characteristics

The following SPICE parameters are extracted:

IS, Transport saturation current

NR, Reverse current emission coefficient

RC, Collector Resistance

ISC, B-C leakage saturation current

NC, B-C leakage emission coefficient

BR, Ideal maximum reverse beta

BETA_MAX, Maximum reverse beta

IKR, Corner for reverse beta high current roll-off
