Amplifiers

[sandeep]

Hi to all ,
I want to know about the different BJT/FETamplifier configurations
about their working and which component is used in them and why?
And how they are used practically?
Thank you.

Common collector circuits.
http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/npncc.html

I saw the end of the above url as meaning something, "npncc =
npn transistor common collector circuit", so I changed the
last c to an e, and as I had guessed, there is the common emitter
circuit.

http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/npncb.html

I try to access the same catalog without a filename
http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/

There are a lot of files with more information here.
http://hyperphysics.phy-astr.gsu.edu/hbase/electronic/npnce2.html
for example, a continuation of ..npnce.html

Hmmm, I found the main index.

And how they are used practically?

The ce stage is the most common circuit, gives good voltage
and current amplification.

The cb stage is used in radio circuits.

The cc stage is often called emitter follower, and is used here
and there in all kinds of electronics.

Here is a table over the characteristics of the 3 basic circuits
for bipolar transistors, scroll down 30% of web page:

The index: http://people.deas.harvard.edu/~jones/es154/
Lots of useful stuff here, and beautiful graphics.

I looked at other papers this guy has on the web.
Here is a little index http://people.deas.harvard.edu/~jones/

His papers lead me to even more valuable texts about electronics.

There is an incredible amount of knowledge and well written texts
on the web, if you can find them.

Here is a bunch of links to electronics tutorials:

But i dont know about good books thats why i asked .
thanx

Thanks for ur kind help.
Thank you very much
