OP AMP INTEGRATOR CIRCUIT DESIGN AND WORKING
The OP AMP Integrator , is a circuit which performs the integration of an input signal. The output of an integrator will be the mathematical integral value of continuous input signal. Such a circuit is obtained by using a basic inverting amplifier configuration if the feedback resistor Rf is replaced by a capacitor Cf. V o = -1/R 1 C F ∫ 0 T (Vin dt + C) The above equation shows that the output voltage is directly proportional to the negative integral of input voltage and inversely proportional to the time constant R1Cf.
