Power bipolar transistors are semiconductors in which a base n-type or p–type layer is sandwiched between emitter and collector layers of the opposite type. There are two polarities available: PNP and ...

Transistors in some circuit configurations work together and, frequently, need to be matched. This is so common that you can sometimes find ICs that are just a pair of transistors made with the same ...

Back to analog, let us start some Schmitt trigger experiments with jellybean bipolar junction transistors… This post explores the classic emitter-coupled Schmitt Trigger circuit. A Schmitt trigger is ...

This book is designed for students who are taking their first course in analog electronics in either a two-year or four-year program. The prerequisites are a DC-AC course; a basic knowledge of algebra ...

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 first ...
