Hint for P14-10

The figure shows that the output voltage should be 0.5 V when the input waveform has a slope of 0.2 V/ms. What value should R have?

Determine the desired breakpoint frequency by determining the intersection (on a Bode plot) of the gain of the differentiator (2 pi f Rf C) with the overall op-amp rolloff expression: 1.0 MHz/f. Set the value of the stabilizing resistance accordingly.
