It’s the mid 1990’s and I am a design engineer for a company that designs and manufactures custom measurement systems and high power electronics. Our customers range from experimental fusion reactor ...
The invention of the transistor in 1947 by Shockley, Bardeen and Brattain at Bell Laboratories ushered in the age of microelectronics and revolutionized our lives. First, so-called bipolar transistors ...
In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...
A dramatic exception is the ΔVbe effect, in which ordinary small signal BJTs can function in simple circuits as 0.1% ...

What Is a Transistor, and How Does It Work?
How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material. Most transistors have three terminals, often ...
