Unformatted text preview: Report 10: Differential Amplifiers Name: Lab Section: 3.2.2 Measure IC 1 , IC 2 , IC 3 , and VOUT,DC . How do they compare with your hand calculations? IC 1 = IC 2 = IC 3 = VOUT,DC = 3.2.3 Sketch the waveforms at vin+ and vout+ . 3.2.4 Measure the peak-to-peak voltages of vin+ and vout+ . vin+,p−p = vout+,p−p = 3.2.5 Qualitatively describe vout+ and vout− (i.e their similarities and differences). Is this result agreeable? 3.2.6 Measure the peak-to-peak voltage of vout+ − vout− and calculate the differential gain of the circuit. Does this match the gain you calculated in the prelab? 1 2 vout,p−p = ADM = 3.2.7 What do you see at the output? Why? 3.2.8 Measure the gain. Does it match your prelab calculations? Does it match your result from 3.2.6? ADM = 3.3.2 Sketch the output waveform. Why is it not sinusoidal? 3.3.4 Calculate the differential gain of the amplifier with the added load resistor. ADM = 3.3.5 Sketch vout . What is the measured differential gain of the circuit? How does it compare with your hand calculations? Does it match the gain you observed in step 3.2.6? Should they match? ADM = 3 3.4.1 Attach your netlist to this report. 3.4.2 Use SPICE to find IC 1 , IC 2 , IC 3 , and Vout,DC . Compare these values with your prelab calculations and lab measurements. IC 1 = IC 2 = IC 3 = VOUT,DC = 3.4.3 Attach your plot to this report. What is the gain according to the plot? Does it match your hand calculations? Does it match your labs measurements? ADM = ...
