Loop Compensation
(Continued)
A second zero can also be added with a resistor in series
with Cc2. If used, this zero should be placed at fn, where the
control to output gain rolls off at -40dB/dec. Generally, fn will
be well below the 0dB level and thus will have little effect on
stability. Rc2 can be calculated with the following equation:
