    i have a question about current adjustment.

    if i have 2 circuits one acting as a current source and the other one as a current sink that is sinking the current of the first one, what do i have to consider to make this work?

    I know, that the sinking circuit has a very low input impedance. How do I have to design the output impedance of the first cirucit to get a current flowing there?

    for which keywords could I search?

    regards antonio
