analog integrator 1

[230842]

For magnetic messurements purposes I'm trying to build an analog integrator. The objectives require an OP amp, or similar, whith an offset voltage lower than 10 microvolts and biass currents lower than 10 picoamps.
Any help will be appreciated regarding Op amp type or any other suggestion. Julian

OP07 is a very low offset op-amp .it's offset is in range of microvolts.I think it's suitable for your purpose
