    35:38 Answer :
    The junction is very close to emitter since more is the doping less is the width of depletion layer in that part and as the emitter is heavily doped therefore the depletion layer in it is very thin and hence the junction is near it.

    Two diodes connected in reverse polarity, does it work as a transistor? Can u please tell sir? The lecture was very nice. Thank you very much Sir.

      It can be thought of like that but it is not. Because that circuit may look like a transistor but it cannot perform the functions of transistors.
      You can draw yourself circuits in a notebook and analyze the differences between your circuit and transistor.

    I think the junction should be away from the emitter towards the base. (as it is lightly doped)

  • @gullibhorga-vd3jf

    Junction should be away from the emmiter becouse it is heavily doped and thants why it shorten the deplition layer btw emiter and base junction.

    • @saicharanmarrivada5077
      @saicharanmarrivada5077 4 роки тому +4

      Yes bro it's done to avoid punch through , if doping is less in the base region then depletion region on the base side will be wider and transistor action is lost . Also we want early voltage to be as high as possible ,so collector capacitance has to be higher which means depletion region on collector side should be wider

      43:22 , you cannot have accumulation of charges , if recombination happens in base , charges accumulated, you inject base current so as to keep no. Of holes in base alive and constant
