op amp psrr
Hi,
in order to find the input offset voltage, connect the op amp as a buffer (Av=1 V/V)...then sweep the dc connected at the input (let say from 0 to Vcc)...then plot the input and output waveform versus dc input....
then you will see the two waveforms, i.e. the input and output wave forms, that do not overlap to each other. the distance between them is the offset voltage. if they are overlapping to each other, then there is no offset voltage.
hope can clarify your question.
thx
