A.3 Simulation Setup of the Diode Example

This section contains the simulation setup for the small-signal simulation of the diode.

Device
{
   +Contact1 = 0.0 V;
   +Contact0 = step(-0.8 V, 0.8 V, 0.1 V);

   +acContact1 = 0.0 V;
   +acContact0 = 1.0 V;
}
Solve
{
   ac = yes;
   frequency = step(1 Hz, 1e20 Hz, 10, log=yes);
}

In the device section (not completely shown here) the terminal conditions are set once for the DC operating points and once for the AC systems. Note the prefix ac of the name of the terminals. The DC anode voltage is stepped by $ 0.1\,$V from $ -0.8\,$V to $ +0.8\,$V.

As seen in the previous section, the frequency domain is defined in the Solve section of the input-deck. The simulation consists of a logarithmic frequency stepping from $ 1\,$Hz to $ 10^{20}\,$Hz with a multiplication factor of 10.
