Why “Transistor Action”?

Aside from sounding cool, I think that this name is meaningful in two ways. Firstly, it is sometimes used to refer to the process that causes the current gain in BJTs. This involves a small back injection current from base to emitter resulting in a much greater linking current from collector to emitter, when the emitter is much more highly doped than the base.

I think that the term “transistor action” also captures the excitement of putting BJTs and other components to use in neat projects. I love the creativity in involved in design and the sense of accomplishment upon constructing a circuit.
