WebThe Zener forms an inexpensive “floating” shunt-regulated supply for the first op amp. The N-MOSFET drain delivers a metered current into the virtual ground of the second stage, configured as a transimpedance amplifier (TIA). The second op amp is powered from a positive supply and furnishes a positive output voltage for increasing load current.

To measure uAs, your current shunt should have a resistance value roughly in the 100s of Ohms or greater. You don’t want to have a very low resistance shunt (say 5 Ohms), with a very large Op Amp Gain, because the shunt will produce very little voltage (5Ohms *150uA = only 750uV). dictatorship games

"WebOp-Amp Biasing Using a Linear Voltage Regulator. For op-amp circuits operating from the +3.3-V standard, a +1.65-V biasing voltage is needed. Zener diodes are commonly available only down to +2.4 V, although the 1.225-volt AD589 and AD1580 bandgap shunt regulators can be used like Zener diodes to provide a fixed—though not centered—voltage at low … " - Op amp shunt
