Transistor

  • In 1951 , William- First junction transistor, a semi conductor device that can amplify electronic signals.
  • Before this, vacuum tubes were used.
  • Advantages of transistor:
    • Low operating voltage
    • Higher efficiency
    • Small size and ruggedness
    • Does not require any filament power
  • Three terminal device: Base, emitter and collector
  • Three configurations: Common base, common collector, common emitter
  • According to application, can be used for voltage as well as current amplification.
