... Many op amps are internally compensated. Internal frequency compensation capacitor prevents the op amp from oscillating by decreasing the op amp's gain as frequency increases. Otherwise there would be sufficient gain and phase shift at some high frequency where enough output signal could be fed back ...

... Error terms are the same as for the inverting amplifier (see MT-213). Most significant is the offset term. The frequency response of the circuit is set primarily by the open-loop gain of the op amp. The shunt capacitance of the diodes and the diode turn-on/ turn-off time can also affect the frequenc ...
