1. Design a non-inverting op-amp circuit which will provide a gain of +2. A large feedback resistor tends to produce better results (10 K ohm suggested) Construct and test your circuit. When you are satisfied with your design, have the instructor check your circuit to verify that you have designed and built your circuit correctly. Include a schematic showing your non-inverting op-amp design in your lab report. а 2. What is the acceptable range of input voltages that can be amplified correctly by your non-inverting op- amp design? Why are the voltages in this range acceptable? To answer these questions, construct the circuit below. Use the function generator to make a triangle wave as the input to your amplifier and measure the input and output voltages of your amplifier. Adjust the function generator amplitude so that the scope output shows which voltages are and are not amplified correctly. Include a clearly labelled screenshot in your memo - a picture is worth a thousand words. Vin Vout Your Circuit Schematic Function Generator Scope Channel 1 Scope Channel 2 Ground Ground) Figure 5 3. Normally the scope is used to display a voltage vs time. You may find it interesting to put the scope in X-Y mode to view the output voltage (ch2) vs the input voltage from the function generator (ch1). The X-Y mode is available from the "Display” menu. If you reduce the frequency to 0.2 Hz you can get a good understanding of how the trace is generated. I recommend that you include this graph in your memo- the boss did not ask for it, but it's always a good idea to provide more value if you can.
