Capless regulator overshoot and undershoot regulation circuit |
摘要 |
Systems and methods for reducing voltage undershoot and overshoot of a voltage regulator are disclosed. In one embodiment of the present disclosure, an undershoot/overshoot regulation circuit comprises a control node having a control voltage. The regulation circuit also comprises a control circuit configured to increase the control voltage in response to a load being applied to an output node of a voltage regulator and decrease the control voltage in response to the load being removed from the output node. The regulation circuit also comprises a control capacitor including a first terminal coupled to the control node and a second terminal coupled to a gate node of the voltage regulator. The control capacitor is configured to increase a gate voltage at the gate node in response to the increase of the control voltage, and decrease the gate voltage in response to the decrease of the control voltage.
