Hi Tosei,
As I understand, you are designing an InAmp with discrete op-amps. Am I right?
In that case, if you want to use current-mode op-amps following Steve's suggestion, you could take a look on this big appnote from Analog Devices:
http://www.analog.com/static/imported-files/design_handbooks/5812756674312778737...)
There is a lot of info there and part numbers that maybe you could use.
Now if you are designing an integrated InAmp, you might want to take a look at the following references:
B.J. van den Dool, J.H.Huijsing, "Indirect Current Feedback Instrumentation Amplifier with a Common-Mode Input Range that Includes the Negative Rail," IEEE J. Solid-State Circuits, Vol.28, No.7, pp. 743-749, Jully 1993.
C. Toumazou, F. J. Lidgey, "Novel Current-Mode Instrumentation Amplifier", Electronics Letters, Vol. 25, No. 3, pp. 228-230, Feb., 1989.
In Toumazou's paper, a discrete realization is described, but an integrated one would be better in terms of matching.
Regards,
Paulo
