Op-amps III, the op-amp integrator

 

Experiment 1:

                    R2 = 100k is ommited from the calculation                    No, R2 contributes a big enough impedence for the gain so that the output just doesn't rail off to infinity.                     No                    Yes, the phase is not far off 90 degrees which was calculated

Experiment 2:

Opting for a smaller capitance led to a larger resistance. It was much simpler to obtain an output swing between 1 and 4V by using a pulse from 0 to 5 since the common mode voltage has been centered around 2.5V like the previous labs.
