Object<\/strong>: Study of Differentiator using Operational Amplifier.<\/p>\n\n\n\n

Apparatus Required:<\/strong> Bread Board, 741 IC, \u00b112V supply, Resistors, Capacitor and connecting leads.<\/p>\n\n\n\n

Theory: In the differentiator circuit the input is connected to the the inverting output of the Op-Amp through a capacitor(C) and a negetive feedback is provided to the inverting input terminal through a resistor(Rf), which is same as an integrator circuit with feedback capacitor and input resistor being replaced with each other. Here the circuit performs a mathematical differentiation operation, and the output is the first derivative of the input signal, 180′ out of phase and apmlified with a factor Rf*C. The capacitor on the input allows only the AC component and restrict the DC, at low frequency the reactance of capicitor is very high causing a low gain and high frequency vice varsa but and high frequency the circuit becomes unstable.<\/p>\n\n\n\n

  2. + Vcc and – Vcc supply is given to the power supply terminal of the Op-Amp IC.<\/li>\n\n\n\n
  3. By adjusting the amplitude and frequency knobs of the function generator, appropriate
    input voltage is applied to the inverting input terminal of the Op-Amp.<\/li>\n\n\n\n
  4. The output voltage is obtained in the CRO and the input and output voltage waveforms
    are plotted in a graph sheet.<\/li>\n<\/ol>\n\n\n\n
