Transistors

The invention of transistor by scientists William Shockley, John Bardeen and Walter Brattain at AT&T Laboratories at New Jersey in the USA has revolutionised the electronic devices resulting in various applications of electronics and communication engineering fields around the universe.

The family of transistors consists of

1. Bipolar Junction Transistors (BJTs)

   (N-P-N Transistor and P-N-P Transistor)

2. 1. Junction Field Effect Transistors (JFETs)

      (N-Channel JFET and P-Channel JFET)

   2. Metal-oxide Semiconductor Field Effect Transistor (MOSFETs)

      Enhancement MOSFETs; Depletion Enhancement MOSFETs

3. Unijunction Transistor.
