Hi everyone, In my thread last week Peter posted a schematic for a virtual shunt current measurement circuit. I wanted to know more about this type of circuit, but a search on "virtual shunt" combined with some other terms turned up no useful links. Could this type of circuit have a different common name? Also, if anyone has suggestions or tips for measuring small (10nA-100uA) currents feel free to share them! :) Thanks.
