When we meet operational amplifiers, we will manage to make nearly-ideal integrators, and pretty good differentiators. A similar effect can be achieved, however, by limiting the gain above some frequency. In order to overcome the limitations of the ideal differentiator, an additional small-value capacitor C 1 is connected in parallel with the feedback resistor R, which avoids the differentiator circuit to run into oscillations (that is, become unstable), and a resistor R 1 is connected in series with the capacitor C, which limits the increase in gain to a ratio of R / R 1.
