Hi, this is my first post so be patient.
I have to design for projekt precise current-to-voltage converter for A/D converter. I'm using 0.35um technology in cadence (amsc35b3). It should convert current 0-10mA to -1-1V voltage. Is there any ideas besides precise resistor or operation amplifier with one resistor as I-V converter? I need a circut schematic for simulations. I will be thankfull for any help
 

use a transimpedance amplifier. with the feedback resistor as off-chip. Or else, if you want only on-chip resistors, use an R-Bank so that you could tune it to the exact value after the chip comes back
