Two-region saturation at high injection levels and at low frequencies may be conveniently approximated using a graphical model which introduces the concept of quasi-saturation resistance R/SUB QS/. It is shown how this graphical model may be implemented in the modeling program SPICE with the aid of a distributed equivalent circuit.
