Bipolar Junction Transistor

BJT or Bipolar junction transistor consist of three terminals. They are base, emitter and collector. It is used for amplification of weak signals and switching operations. It has two types of physical structures namely PNP and NPN. IN PNP, N type semiconductor is sand-witched between two P type semiconductors. In NPN, P type semiconductor is …

Bipolar junction Transistor – BJT

Posted by on

Emitter is moderate size and heavily doped. Collector is large in size and moderately doped. Base is thin and lightly doped. When collector supply is 5V then collector cut off voltage is 5V. Zero signal condition is when transistor see dc load. Cut-off region – both junctions are reverse biased, Saturation region – both junctions …
