With variation of the incoming signal and thus the base current there is a corresponding change in the collector current dictated by the transistor’s gain, and thus an output voltage is ...

The diagram illustrates the basic design of an NPN junction transistor. Two slices of N-type semiconductor, the emitter and the collector, form a sandwich with a layer of P-type semiconductor ...

If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

The transistor base (the "meat" of the sandwich ... The two slabs of "bread" (one is called the emitter and one is called the collector) have excess electrons. These electrons can scoot around ...

Double heterojunction bipolar transistor, Non-uniform material, Early effect, Emitter bias dependence, High-level injection, Base, emitter and collector transit times, and RC time constant.

Once an input of 0.6 volts has triggered the base leg, a much larger current can flow through the collector or emitter leg. Transistors are easily damaged so it is important not to mix up the ...
