How Active Devices Work CPARC Talk

Last month, I gave a relatively long talk at the biweekly CPARC meeting on the principle of operation of diodes and three-five terminal devices. This included bipolar transistors, field effect transistors, and vacuum tubes ranging from triodes to pentodes.

Vacuum tubes, part 2 of 2:


Needless to say, there are numerous technical flubs made during this two hour long talk without notes. One that particularly stood out was that I managed to get the polarity of electrons wrong when I was explaining the suppressor grid of a pentode.  Damn you Benjamin Franklin!

If you catch any other glaring flubs or mistakes, please feel free to post in the comments.

  1. I watched both videos and it jogged my memory of high school electronics, 1962, and the study of vacuum tube theory. Just as interesting today as back then.
