How to Build a Photodiode current to voltage converter

The Photodiode current-to-voltage converter schema uses three CA3130 BiMOS op amps in an application sensitive to sub-picoampere input currents. The schema provides a ground-referenced output voltage proportional to input current flowing through the photo-diode.
