Spice-style bipolar base resistor of the analog electrical library

## Information

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)
