The realization of a differentiator is challenging, because the gain increases with the frequency, where the operational amplifier has a phase shift of at least 90°. So, when there is a capacitor at the input to the inverting terminal and a resistor with one side connected to the inverting terminal and the other side to the output, we have a differentiator circuit. Practical Op-amp Differentiator Circuit. This is due mainly to the first-order effect, which determines the frequency response of the op-amp circuit causing a second-order response which, at high frequencies gives an output voltage far higher than what would be expected. To insure stability a designer can add a feedback capacitor that is rather large, thus overcompensating the circuit. Thus to avoid this resistance Rc is added in series with capacitor C and a capacitor Cc is added in parallel with resistance R. The practical differentiator is shown below.

However, at high frequencies an op-amp differentiator circuit becomes unstable and will start to oscillate. In process control, the derivative function is used to make control decisions for maintaining a process at setpoint, by monitoring the rate of process change over time and taking action to prevent excessive rates of change, which can lead to an unstable condition. fast fast! two integrators and a differentiator circuit. Differentiating Circuit A circuit in which output voltage is directly proportional to the derivative of the input is known as a differentiating circuit. A differentiating circuit is a simple series RC circuit where the output is taken across the resistor R. The circuit is suitably designed so that the output is proportional to the derivative of the input. Ideal Op-amp Integrator Circuit An op-amp integrating circuit produces an output voltage which is proportional to the area (amplitude multiplied by time) contained under the waveform. When the capacitor phase shift is added, the phase margin becomes zero or negative, and the circuit tends to become unstable. Here Rc and Cc are called as compensating components. This familiar relationship implies that a Bode plot for the gain of an idc.il integrator will have slope -20 dB/decade, or -6 dB/octave. An ideal op-amp integrator uses a capacitor C1, connected between the output and the op-amp inverting input terminal, as shown in the figure below. At high frequencies the gain of the ideal differentiator is very high. When a signal, v i (t), is applied to the input terminal the output will be the derivative 3 with respect to time of the input signal multiplied by a constant factor. These problems can be avoided or corrected in a practical differentiator circuit which uses a resistor R1 in series with the input capacitor and a capacitor Cf in parallel with the feedback resistor, as shown in the figure below.
