COUT = 660 mF
RESR = 3 m
The theoretical waveform is plotted in Figure 12. For comparison purposes, the measured data is in Figure 13.
Note the excellent correlation between the theoretical and actual data. In both cases, the 0-dB bandwidth is
approximately 25 kHz, and the phase margin is >90 degrees! As a result, creating the desired loop response is a
matter of adding a DC gain component (if a load-line is allowed) or adding an appropriate pole-zero or
pole-zero-pole compensation

Function
Limit the overall open-loop bandwidth below of fS to avoid violating the Nyquist Criterion. Also, for the best
performance of the modulator, the characteristic of the compensation should be resistive at the switching
frequency. With this in mind, a zero frequency in the range of 10% to 20% of fS is recommended.
