Hello everyone,
In my lab class we've been given task of using op-amps to amplify a current of 1nA and frequency of order of madnitude 1MHz to a discernable level. We've been given breadboards, a selection of different op amps, resistors, an oscilloscope etc to achieve this task. We've made good progress so far as we've gotten down to 10nA. But at 1nA we get to much noise to make a discernible waveform on the oscilloscope. Does anyone have any tips on how we may go about reducing noise in this setup?
Thanks for your time
