It contains practical advice on using operational amplifiers and how to prevent some common problems. The difficulty lies in knowing where to start and when to apply the rules. The op amp obeys the input-output relationship: where v o is the output voltage, v + and v-are, respectively, the voltages at the non-inverting and inverting inputs, and A is the amplifier gain. Because op-amps have such a large gain they are useful for feedback configurations, as we will see. The two op-amps currently used are the known 741 chips. In this circuit the ‘non inverting’ terminal of second op amp is grounded, to get sawtooth generator we just need to add a potentio meter arrangement. Unlike the integrator circuit, the op amp differentiator has a resistive element in the feedback from the output to the inverting input. For the op-amp with finite gain and bandwidth, the V−terminal is not a virtual ground so that the input impedance differs from R1. Opamp integrator circuit. I think the issue at hand might be that the op amp is switching on and off far too quickly. Such a circuit is obtained by using a basic inverting amplifier configuration if the feedback resistor RF is replaced by a capacitor CF.

Because of their wide range of uses, op-amps are encountered in most electric circuits. The op-amp tries to keep its two input terminals at the same voltage, so as the non-inverting (+) input changes, the op-amp tries to output whatever voltage it can to get the inverting (-) input to the same voltage. To reduce the magnitude of the output offset, we can reduce the size of RF. You can put together basic op amp circuits to build mathematical models that predict complex, real-world behavior.
