Here is an interesting op-amp circuit which - it is claimed - can be used to integrate a signal.

Your task in this exercise is to do the following.

• Use these values for components:
• R = 10 kW.
• C= .22mf.
• Using a sinusoidal signal as an input,
• Derive the output signal when the input is a sinusoidal signal.
• Measure both the input and output on an oscilloscope so that you can compare phases to determine that integration is really taking place.
• Make sure that the output is the right magnitude.
• Using a square wave signal as an input.
• Determine what the output signal should look like.
• Measure both the input and output on an oscilloscope so that you can compare them to be sure you understand what is happening.

• Click here for a report form you can print.
• You may want to consider using a large resistor in parallel with the capacitor.  Many times signal generators will have a DC offset in the output voltage.  If you have even a small DC offset in the output, think about what that does to the output.
