An integrated circuit for providing a reference signal to a regulator includes a comparison circuit and a first reference signal adjustor. The comparison circuit is configured to output a control signal based on a difference between levels of a constraint signal of the regulator, such as an input voltage signal or a supply voltage signal, and the reference signal. The regulator has a feedback control loop maintained by the reference signal. The first reference signal adjustor is operatively coupled to the comparison circuit and is configured to adjust the level of the reference signal based on the control signal such that the level of the reference signal increases toward a preset level and does not cause the feedback control loop of the regulator to become saturated when the regulator is in a start-up phase. |
