    Hello,

    The title says all.
    Can you please sugest me an experimental procedure to determine the offset voltage and input bias current of a 741 opamp and also ?

    Thanks in advance!

    Polarization current is not a normal op amp specification. Do you mean offset or bias current?

    I mean input bias current.
    Sorry, im portuguese and that was a bad translation in deed.
