Op-Amp Integrator Circuit | Using Op-Amp | 741 IC | Linear Integrated Circuits Lab Experiments. Diploma Polytechnic Students Aim: To design and setup an integrator circuit using OP AMP 741C and plot its pulse response. Equipments/Components: Sl. No Name and Specification Quantity required 1 Dual power supply +/- 15V 1 2 Function generator (0-1MHz) 1 3 Oscilloscope 1 4 Bread board 1 5 IC 741C 1 6 Resistor 1 7 Capacitor 0.01μF 1 8 Probes and connecting wires As required. Principle: It is a closed loop op-amp circuit which performs the mathematical operation of integration. That is the output waveform is the integral of the input voltage and is given by Vo = ( -1/RfC) ∫Vindt. The integrator circuit is constructed from basic inverting amplifier by replacing the feedback resistance Rf with capacitor C. This circuit also works as low pass filter. Procedure: 1. Check the components. 2. Setup the circuit on the breadboard and check the connections. 3. Switch on the power supply. 4. Give Vi= 2Vpp, 1KHz square wave. 5. Keep the oscilloscope in AC coupling mode. 6. Observe input and output on two channels of the oscilloscope simultaneously. 7. Draw the input and output waveforms on the graph. Design: Given f =1 KHz So T = 1/f = 1ms Design equation is T = 2πRiC Let C = 0.01μF Then Ri = 15KΩ Take Rf = 10Ri = 150KΩ
