Hmm. so, where were you, when there were over 40 posts, a
link to several circuits 5 months ago on this idea ??

Probably not paying attention. If there were lots of Joot and Middius posts
involved I may simply not have bothered looking.


The only way the anode voltage can have a changing influence
by electrostatically influencing the space charge around the cathode,
is when it ^actually^ changes, eh ?
so, lock the anode voltage, he, presto, no fb, no Miller, because
the inherent fb mechanism is not used

Also true in cascode circuits.
