在差分输入端，采用正反馈电路结构，以提高开启和关断速度，并降低功耗。

In the differential input, positive feedback circuit was used to increase the switching speed and attain low power.

这样不仅可以做到速度的实时反馈和调整，而且由于PI调节器的积分作用，可以使系统在稳态时做到速度无静差。

So it not only achieves the real-time feedback and the regulation of speed but also eliminate the static error of speed due to the integral action of PI regulator when the system is in a steady state.
