OPA171 - the improvement of phase margin and gain margin

Other Parts Discussed in Thread: OPA171, TINA-TI

Hi all,

Would you mind if we ask OPA171?

We simulated the phase margin and the gain margain on Tina-TI following files.(using  Middlebrook method)

OPA171_stab05_for_test .TSC

The value of phase margin and gain margain is requried each followings;
-Gain margin: 10dB
-Phase margin: 60degree

We changed the value of feedback capacitances(C1, C2 from 1pF to 100nF) and C3, C4(1pF to 100nF) 
However, we could not get target value of gain margin and phase margin.

So, how much of value are good for C1, C2 to prevent oscillation?
If you have some advice, could you let know us?

Kind regards,

Hirotaka Matsumoto
