The input is connected to a resistance while the output voltage is taken from across a capacitor for a passive RC integrator circuit (being the exact opposite to the RC Differentiator Circuit). An operational amplifier, abbreviated as op-amp, is basically a multi-stage, very high gain, direct-coupled, negative feedback amplifier that uses voltage shunt feedback to provide a stabilized voltage gain. Solution for Design an integrator circuit and a differentiator circuit with τ = 1 ms (hint: use a 100 nF capacitor for both). Perhaps the most obvious extension is to add multiple inputs, as in an ordinary summing amplifier. The limitations of an ideal integrator can be minimized in the practical circuit by adding resistor Rf in parallel with capacitor C this Rf avoids op-amp going into open loop configuration at low frequencies.
