Analog derivative controllers have a capacitor in the feedback path and integral controllers have a capacitor in the input path of the amplifier.

Question

Quizplus · Accepted Answer

Analog integral controllers have a capacitor in the feedback path to achieve integration over time, while derivative controllers often use a capacitor in the input path to achieve differentiation, but the specific configurations can vary depending on the design.
