In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object ...

[Ben Krasnow] put together a tutorial in which he does an excellent job of explaining the ins and outs of designing transistor control circuits. We’ve embedded his twenty-minute video after the ...

Transistors had become commonplace in everything ... That spring, Fairchild began a push to build what they called "unitary circuits" and they also applied for a patent on the idea.

and there is a load resistor to ground in the emitter circuit. As with both of the other configurations, the bias is set such that the transistor is turned on and passing a constant current that ...
