who can give a paper compare all buffers in op-amps?

[mike_bihan]

thanks,

book name is also ok.

i don't beleive you will find something like it. Can you explain the problem or are you looking for it for academic purposes only?

 

[mike_bihan]

I just want to have some good article on when to use which kind of buffer in the OP-AMP. Thanks

mike,
i don't understand. are you looking for comparison of op-amp architecture (miller, cascode, folder) or comparison of op-amps used as buffer?

for buffer, use a hi-gain miller op amp compensated for unity gain

 

[mike_bihan]

sorry for the confusion, I mean the buffer as "output stage buffer", sorry!

Good book:

"Design of low-voltage low-power CMOS operational amplifier cells" by Ronald Hogervorst, Univ. of Delft Press
ISBN 90-407-1339-1
NUGI 841

See Chapter 4 for output stages ...
