Hello , In the system below there is a mode i am trying to couple.
at weak coupling I get a certain surface current responce and in stronger coupling I have different responce as shown below.
How can I see from the surface currents where can i improve the coupling in my model?

Thread 'uA709 op amp compensation'

Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
