OP_amp
Dear ALL,
I have confuse by the analysis of diff amp and op amp.
Here, my question. When we try to write a transfer function for a om_amp (please refer to file name op_amp), we will assume the v- is virtually short to v+. Why can we assume that?
Since we know the input part of the op_amp is a diff_amp, when we analysis diff_amp, can we make the same assumtion?
THanks
