Extraction of bipolar SPICE Gummel-Poon parameters related to B-E junction Capacitance-Voltage (C-V) characteristics

The following SPICE parameters are extracted:

CJE, B-E zero-bias depletion capacitance

VJE, B-E built-in potential

ME, B-E junction exponential factor

FC, Coefficient for forward-bias depletion capacitance
