(If this op amp were operated in a buffer configuration, it would have a phase margin of 43 degrees.) If the op amp were used in an inverting configuration with a gain of one, K would be 0.5 or -6dB ...

Before going into op amp compensation it is important to shed some light on two most basic configurations in the op amp; the non-inverting (Fig. 1.A) and the inverting (Fig 1.B). There is plenty of ...

2. In an inverting and single non-inverting input op-amp summer, R1-R3 interact to some extent (Equation 2). Equation 2 is still manageable: R1-R3 are interactive, but not terrible to deal with. 3.

Other practical problems arise because the op amp isn’t really perfect. A real op amp would not hit the 15V rail exactly. It will get close depending on how much current you draw from the output.

An op amp with +/-15V on the rails can’t produce 50V to wrestle the input to a particular value. But for common sense applications, those assumptions will take you a long way.
