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 . . .

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor. It starts charging when the ...

Stacks of transistors built from nanomembranes that can be rolled onto a substrate have been used to fabricate 3D circuits. A transistor is a device that controls the flow of current in a circuit. In ...
