Hi vecky,
What is your supply voltage & load resistor/current pls?

Added after 33 minutes:
If you has a simple DC-signal (not on HV or line...); refer pls at https://en.wikipedia.org/wiki/Op_amp to "Basic single stage amplifiers, Non-inverting amplifier".
Gain is 1+R2/R1, with i.e. 3.3K as R2 & 1K =R1 you have it as a noninverting amp, as one possibility...
I would select a modern CMOS or BicMOS OP (TI, Maxim, Micrel, NI, ON Semi...) with rail to rail I/O.

Thanks Everyone on answering I need that for one unimer which output is on uA with voltage in range of 0V-1V and range 100 Ohms-0 Ohms but I want to amplify the range of 10 Ohms- 0 Ohms and How?
I though the in serial put one fast diods with voltage drop about 0.4V and thats fine I measured thats work fine. I need something to amplify that signal after that on 1V. and if that go fine it means that I can go further in 1 Ohms- 0 Ohms. But I am not sure on precission after all of that.
What do you think?
