An NPN transistor has three legs. In circuit diagrams or symbols, the legs of an NPN transistor can be identified as follows: Base (B): Usually located in the middle.

Field-effect transistors fabricated from carbon nanotubes have been investigated extensively over the past two decades. This study demonstrates a nanotube-based integrated circuit design that ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

A flip-flop is one of the most basic digital electronic circuits. It can most easily be built from just two transistors, although they can and have been built out of vacuum tubes, NAND and NOR ...

This automatic battery-charger, built around a single transistor, starts charging when the battery voltage drops beyond a preset value and stops when once an upper preset voltage is reached.
