The common base amplifier, on the other hand, ... Makes sense for BJT circuits, because bipolar transistor base takes much more current than a vacuum tube grid.

Jenny, I love this series, but paragraph 4 of the common emitter biasing discussion should say, “In an NPN transistor, the connection between base and emitter is a PN junction, so as you might ...

Immediately, I learned that the common base configuration gain was 6db lower than the common emitter. This blew my mind. Then I started checking input resistance and was shocked at how low it measured ...

OK, so I get a press release (pdf) from those wonderful folks at CamSemi, AKA Cambridge Semiconductor. It talks about their C2163 off-line switcher chip (pdf). The press release says: “…the BOM cost ...
