Circuit Analysis II TEET 3145 Laboratory # 6 OP Amp Integrator and Differentiator Fall 2009 Georgia Southern University Mechanical and Electrical Engineering Technology Page 1 of 2 Name: ________________________ Your Partner Name: ________________________ PreLab Before going to the lab, use MultiSim to simulate the circuits in figure 2 and 3. Use the input signals defined in sections: Integrator and Differentiator. Print out the results of your simulations and take them to the lab to compare the simulated results with the ones you will get in the experiment. Use the 741 op amp. Introduction The operational amplifier of op amp is a high performance linear amplifier with an amazing variety of uses. The op amp has two inputs, inverting ( – ) and non-inverting (+), and one output as shown in figure 1. The polarity of a signal applied to the inverting input is reversed at the output. A signal applied to the non- inverting input retains its polarity at the output. The pinout diagram for the LM741 op amp IC is shown in figure 1. Use this to construct the op amp circuits in this experiment. Figure 1. Pinout for the 741 op amp 1.- Integrator The name "operational amplifier" came from this amplifier's ability to perform mathematical operations. Two good examples of this are the integrator and differentiator which perform the operations of integration and differentiation, respectively. Construct the integrator shown in figure 2. Sketch the input and output waveforms for the following input signals a) sine wave, Vp = 1V, f = 500 Hz b) triangle wave, Vp = 1V, f = 500 Hz c) square wave, Vp = 1V, f = 500 Hz For your report, include your sketches and show that the output waveform is indeed the integral of the input waveform. Note that the 10MΩ resistor (a very large value) is not in the ideal integrator circuit. What is it there for? (Think about what would happen if a small DC component was present in the input waveform. What would integrating this constant do after a short time?) Try removing it and describe what happens. Briefly discuss this in your report. Sketch the Vin and Vout signals obtained in the lab for each of the input waveforms ( sine, triangle and square) .
