In many op-amp applications, wide closed-loop bandwidth isn't as important as low phase shift. Yet in a typical case of an amplifier with a gain of −20, the conventional LM741 has about 0.6° of phase ...
Even the simple circuit of Figure 1 seems to be suffering from a low phase margin condition as described in Reference 1 with a sharp resonance at 165MHz. It is important, even in lower speed signal ...
