Question about feedforward capacitor of integrated DCDC converters

在“Topic 7 - Evaluation and Performance Optimization of Fully Integrated DC-DC Converter”这篇文章里面提到D型电路. Feedback Divider with Capacitor Across the

Bottom Feedback Divider,也可以用来增加相位裕度。

可是从伯德图角度来看,增加了12.2k这个极点后,应该是会减小相位裕度的,希望可以得到专家的解惑。
