Differentiator Amplifier. An Operational Amplifier, or op-amp for short, is fundamentally a voltage amplifying device designed to be used with external feedback components such as resistors and capacitors between its output and input terminals. Integration is basically a summing process that determines the total area under the curve of a function. Here, the op-amp circuit would generate an output voltage proportional to the magnitude and duration that an input voltage signal has deviated from 0 volts. For everything from distribution to test equipment, components and more, our directory covers it. Differential Amplifier. From the diagram, it can be seen that while the input remains at zero, so does the output. Integrator Circuit using Op-Amp On the other hand, there are applications where we need precisely the opposite function, called integration in calculus. A integrator circuit is a circuit that performs the mathematical operation of integration. Mit dem Kondensator wird die Rückkopplung vom Ausgang auf den Eingang frequenzabhängig gemacht.
