Abstract
A slew rate mitigation circuit includes a slew rate mitigation unit, a switch unit, and a control unit. The slew rate mitigation unit is configured to receive an input signal through an input terminal and generate an output signal at an output terminal at a mitigation rate according to the input signal. The switch unit is coupled between the input terminal and the output terminal. The control unit is configured to selectively turn on the switch unit according to the output signal. The switch unit builds a fast charging path from the input terminal to the output terminal when turned on and cuts off the fast charging path when turned off.
