Spice-style bipolar base resistor of the analog electrical library
The base resistor is the most important of the parasitic resistors of a bipolar transistor. For this reason, Spice models this resistor using a more sophisticated model with additional parameters.
Parameters:
RB: Reference zero-bias base resistance (default value = 0 Ohm)
RBM: Reference minimum base resistance (default value = 0 Ohm)
IRB: Current where base resistance falls halfway to minimum value (default value = 0 Amp)
Tnom: Reference temperature (default value = 300.15 oK)
TRB1: Linear temperature variation coefficient of RB (default value = 0 1/oK)
TRB2: Quadratic temperature variation coefficient of RB (default value = 0 1/oK2)
TRM1: Linear temperature variation coefficient of RBM (default value = 0 1/oK)
TRM2: Quadratic temperature variation coefficient of RBM (default value = 0 1/oK2)
Area: Relative area occupied by resistor (default value = 1)
Level: Transistor modeling level (Ebers-Moll = 1; Gummel-Poon = 2) (default value = 2)
