Current-to-voltage converter

[camezcua]

Hi All,


I 'm interesting to build a current to voltage converter with resolution of 1uA to 100uA , the voltage is 2.5VDC.
If somebody know a circuit , please send me a tips .

I will appreciate you help.

Despite the title of the article in this URL, this is really a voltage-to-current converter, which, ironically, may be what camezcua wanted in the first place.
A resistor makes a simple current-to-voltage converter.

Heh, hadnt noticed that. Yeah he did say 2.5 VDC, assuming thats the input.
