A transistor is made of semiconductor, mostly of silicon in present days. Two types of constructions are possible, either a p-region sandwiched between two n-regions or vice versa, as sketched in ...

Many types of transistors are manufactured, with the most quantifiable difference being the methods of construction. The first useful transistor, the bipolar junction transistor, was constructed by ...

[Chuck] has designed, printed and explained the workings of a BJT transistor using a 3D printed model. We really like this model because it goes a long way to shed light on some of the more subtle ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the ...

siblings to the other kind of transistor that’s abundant – BJTs (Bipolar Junction Transistor), popular enough that we typically just refer to them as NPN or PNP transistors. These are all ...

In this module on BJTs (bipolar junction transistors), we will cover the following topics: BJT Device structures, Energy band diagrams, Active bias, Leakage current, Recombination in base, Hoe ...

NPN A physical BJT transistor arrangement where the emitter and the collector are made of N-type material and the base of P-type. PNP A physical BJT transistor arrangement where the emitter and the ...

There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

A type of 3D FinFET transistor from Intel introduced in 2011 with its Ivy Bridge microarchitecture. The Tri-Gate design is considered 3D because the gate wraps around a raised source-to-drain ...

The new type of transistor, known as the "cryo-CMOS transistor," is optimized to operate at temperatures under 1 K and emit near-zero heat. A new type of transistor can dissipate almost zero heat ...
