r2spice function use and calculation of alpha, XIg and Glim
Dear Mr. Nakabayashi,
is there a demo somewhere, with which version of RStudio your r2spice program works?
Parameters a, b and c seem to get calculated using alpha. However it is not exactly described where
alpha comes from - https://ayumi.cava.jp/audio/pctube/node43.html. I assume its discussed more in detail in Yoshinori Ichiki book, however its in japanese and hard to come by.
Also for calculationg xig and Glim its written that xig = Ig/Ik when Vg=Va. So cathode and grid current ratio when plate and grid bias voltage are (positive) and the same. There is no calculation inside of r2spice of these values, yet they are as numbers inside of for example 12AX7 subcircuit.
