Transistors
- The transistor was invented in 1947 by Bardeen, Brattain and Shockley at Bell Labs. It revolutionized electronics. - There are two main types of transistors: bipolar junction transistors (BJTs) and field effect transistors (FETs). BJTs consist of two back-to-back PN junctions that form three regions - the emitter, base and collector. Current flows differently depending on whether it is an NPN or PNP transistor. - Transistors can be used as amplifiers by connecting them in common base, common emitter or common collector configurations and biasing the transistor to operate in the active region. This allows a small input signal to produce a larger
