I don’t mean to downplay the importance of understanding semiconductor physics, but sometimes an intense focus on solid-state physics detracts from understanding these devices’ functions on a component level. Here I want to explore how to use these components, not analyze their intimate internal details. Discussions of holes and electrons are better left to another chapter in my opinion.
My intent here is to focus as exclusively as possible on the practical function and application of bipolar transistors, rather than to explore the quantum world of semiconductor theory. Understanding how transistors function is of paramount importance to anyone interested in understanding modern electronics. This revolution made possible the design and manufacture of lightweight, inexpensive electronic devices that we now take for granted. Technical feats previously requiring relatively large, mechanically fragile, power-hungry vacuum tubes were suddenly achievable with tiny, mechanically rugged, power-thrifty specks of crystalline silicon. The invention of the bipolar transistor in 1948 ushered in a revolution in electronics.
