A.5 Configuration of the Two-Port Features

This section describes the configuration of the equivalent circuit as discussed in Section 3.5. The following keywords in the Contact section are available:

Table A.1: Keywords provided in the Contact section.

Keyword	Type	Default	Description
Z0	Real	$50\,\Omega$	characteristic impedance
parL	Real	$0.0\,$H	parasitic inductance for the two-port calculation.
parC	Real	$0.0\,$F	parasitic capacitance for the two-port calculation.
parR	Real	$0.0\,\Omega$	parasitic resistance for the two-port calculation.

Thus, all capacitances, inductances, and resistances can be defined in the same way as the keyword Z0:

Device : DeviceDefaults
{
   Phys
   {
      +Collector{ Contact{ Ohmic{ parL =  50 pH; parC =  75 fF; }}}
      +Emitter  { Contact{ Ohmic{ parL =   1 pH; parC =  24 fF; }}}
      +Base     { Contact{ Ohmic{ parL =  75 pH; parC = 150 fF; }}}
   } 
}

Solve
{
   calcTwoPortParameters = yes;

   port1  = "Base";
   port2  = "Collector";
   ground = "Emitter";
}

In the Solve section the configuration of the two-port circuit can be found. The two ports are connected to the base and collector terminal, respectively, and the ground is connected to the emitter terminal. By setting the calcTwoPortParameters to yes, the calculation is enabled.
