Abstract: In some embodiments, a Miller compensation and stabilization device for a feedback control loop includes a capacitor and a control circuit. The capacitor has a first terminal configured to be coupled to an output of a comparator of the feedback control loop and a second terminal. The control circuit is coupled to the second terminal of the capacitor and is configured to control, in response to a voltage applied to a setpoint input of the feedback control loop, a first voltage across the first and second terminals of the capacitor by controlling a value of a potential of the second terminal of the capacitor such that the first voltage is lower than a threshold.
