How do they compare with hand calculations?IC1=IC2=IC3=VOU T,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=123.2.5 Qualitatively describe how vout+and vout−are related. Is this what you’d expect?3.2.6 Measure the peak-to-peak voltage of vout+− vout−and calculate the differe ntial gain of the circuit.Does this match the gain you calculated in the prelab?vout,p−p=ADM=3.2.7 What do you see a t 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 isn’t it sinusoidal?33.3.4 Calculate the differential gain of the amplifier with the added load.ADM=3.3.5 Sketch vout. What is the measured differential gain of the circuit? How does it compare to your handcalculations? Does it match the gain you observed in step 3.2.6? Should it?ADM=3.4.1 Attach your netlist on a separate sheet.3.4.2 Use SPICE to find IC1, IC2, IC3, and Vout,DC. Compare these values with your calculations from theprelab and measurements in lab.IC1=IC2=IC3=VOU T,DC=43.4.3 Attach your plot on a separate sheet. What is the gain as measured from the plot? Does it matchyour hand calculations? Does it match your
