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 …
PN junction Diode is formed by joining P type semi conductor and n type semiconductors. Due to diffusion of electrons and holes from P region and N region a depletion layer is formed in between P type and N type semiconductors. This region consist of positive and negative ions. Where positive ions aligned on the …
