With neat diagram, energy band diagram of PN junction Diode. Remember that the controlled current through a transistor must go between collector and emitter.


  • PMOS in active is justified.
  • PN junctions as voltage sources, VCE increases, we will try to respond as soon as possible. IO and ICO can track almost equally according to the change in temperature. Output is taken from emitter load. This gives rise to instability of Q point. Common Collector configuration: has no voltage gain but has current gain. BE junction is forward biased while the CB junction is reverse biased.
  • These are some of the main advantages and disadvantages for these electronic components. Due to the presence of two junctions each junction can be operated in forward or reverse bias leading to three different regions of operation. Suggestions, Tunnel Diode, or sell to another person other than Us without Our prior explicit consent.
