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 ...

[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 ...

The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...

3rd and final course in the Semiconductor Devices SpecializationInstructor: Wounjhang Park, Ph.D., ProfessorThis course presents in-depth discussion and analysis of metal-oxide-semiconductor ...

If we cast our minds back to the early years of the transistor, the year that is always quoted is 1947, during which a Bell Labs team developed the first practical germanium point-contact transistor.
