Simulation von Röhren mit Spice
Georg Beckmann

Ich hatte etwas Zeit, ein Modell einer Triode auf meinen Simulator zu adaptieren. Interessant an diesem Simulationsmodell ist die Möglichkeit, jede Triode anhand von 14 Parametern zu beschreiben.

Wer kann mir helfen, für eine gegebene Röhre diese Parameter aus den Datenblättern zu ermitteln:

*
* THE TRIODE'S 14 PARAMETERS ARE:
*
*     SFS                shape factor of the saturation law.
*     VBIG               contact potential of the grid
*                             (the voltage above which grid may current start to flow).
*     VBIA               contact potential of the anode.
*     MU                  amplification factor at slighly negative grid voltage.
*     RMU                reduction factor for MU at very negative grid voltage.
*     VMU                grid voltage for mid-range MU (negative).
*     SFMU             shape factor for MU reduction law.
*     K                      perveance at slightly negative grid voltage.
*     RK                   perveance reduction factor at very negative grid voltage.
*     VK                   grid voltage for mid-range perveance (negative).
*     SFK                 shape factor for perveance reduction law.
*     SIGMAG         effective cross-section of the grid relative to the anode.
*     ALPHAG        grid current amplification factor.
*     SFG                shape factor of the grid current law.

Das wäre die Liste, noch 2 Bilder von ermittelten statischen Kennlinien

In der Anlage das Modell als subcircuit. Die Endung muss bei meinem Simulator .ckt sein. Es ist ein reines Textfile
