1. The problem statement, all variables and given/known data

hello guys I have an assignment to "Explain six transistor characteristic curves using the construction and operation of BJTs"

I searched all over internet but couldn't find any article relevant.(i found lot of articles about characteristic curves but none of them explained the characteristic curves using BJT construction)

so please could you guys help me with this.I want an explanation of characteristic sing BJT's construction"

Thanks,Hope you guys help me soon

2. Relevant equations

3. The attempt at a solution

First you have to make clear what "curves" you're talking about. There's an IC vs VBE and IC vs VCE for the Ic ones alone. Replace Ic with Ib and you've got another two more graphs. So unless you specify what is meant by the "six transistor characteristic curves", I don't know how to help you.

oh i forgot, its input (Ib- Vbe)and output(Ic -Vce )characteristic curves.

you will get everything you want reg. BJTs and their characteristics in Millman and Halkias text book. please refer..

what is the name of the book

Yeah I agree it's too much to explain here, if you're looking for an explanation right down to the level of semiconductor physics of reverse-bias and forward bias across the BC and BE pn junctions. Your question is basically "How exactly does a BJT work?". Just pick up a textbook on this. I used Semiconductor Physics and Devices 3rd Edn by Donald Neamen

Integrated electronics by millman & halkais
(or)
micro electronics by sedra and smith.
