This article presents the basic analysis and design equations of a 2-transistor configuration using both polarities of transistors: the “complementary” two-BJT configuration. Transistor combinations ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

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 ...
