| The first stage inside the opamp is the differential amplifier shown in the image to the right. This circuit compares the input voltage at the opamp input terminals. The compensation capacitor is at the differential output. If you recall, a capacitor has an exponential charging rate which has a certain slope. When the input signal frequency is high, the slope of the input signal is greater than the slope of the compensation capacitor, as a result, the capacitor can cause distortion known as slew rate distortion. | The first stage inside the opamp is the differential amplifier shown in the image to the right.
