It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier ...
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 ...
Why would a wall-wart design have an external FET driving an external high-voltage transistor? A decade ago, Paul Rako picked the brains of some of the top people in the industry to find answers. When ...
