This is not unique to transistors. Many power tubes will also exhibit such behavior - some more than others. With some tubes signal induced modulation is extremely pronounced. In their case the increase in the internal power dissipation increases the cathode temperature, with corresponding steep increase in emission - hence Gm, etc.Yeah? Not according to Lavardin (see my reply to jcox). Tubes are immune because those li'l ol' electrons are just scootin' along in a vacuum. I guess Lavardin assumes that they just endlessly sail along in a vacuum and never do anything silly like slamming into the cathode. If of course they make it that far without snagging the grid along the way, but that usually only happens with Asian electrons. ;)
Some tubes are even prone to thermal runaways, much like the transistors.
Good thing you said that in here where no one to speak of will read it. Otherwise you might lose a few sales. :)
Thanks for the edification, Victor!
