I am analyzing a common collector BJT as an amplifier using LTSpice. I have made the following circuit and I am not getting the exact characteristics which I should have got.

enter image description here

Is there something wrong in this circuit? It is clear that the polarity of the batteries is correct and we have to vary them to obtain the characteristics. Please help!!

    Your schematic is difficult to "decode" as it does not meet the standard conventions (see: https://electronics.stackexchange.com/questions/28251/rules-and-guidelines-for-drawing-good-schematics/28255#28255), here's an example of how you would want your circuit to look like: https://sub.allaboutcircuits.com/images/03101.png – Bimpelrekkie Feb 14 '18 at 13:07
  • Yes there's something wrong with the circuit as the voltage on the base is **lower** than the voltage on the emitter and since this an NPN the BE junction is **reverse biased**. I suggest starting with re-drawing the circuit as from the picture I mentioned above and take it from there. – Bimpelrekkie Feb 14 '18 at 13:14
  • Try drawing it like this: https://sub.allaboutcircuits.com/images/03101.png – Andy aka Feb 14 '18 at 13:21
  • Describe the characteristics that you have to extract. – jonk Feb 14 '18 at 13:47
  • This figure which you have given link to, is not a Common Collector. – Himanshu Sharma Feb 15 '18 at 10:28
  • Try drawing the circuit using the tool provided by stack exchange. Also, can you tell us what's "wrong" in the output? that will reduce the "guessing" time for us. – himura Feb 20 '18 at 08:44
