Abstract
A voltage-regulator device includes an error-amplifier stage configured to receive a first reference voltage and a feedback voltage, an output amplifier stage coupled to the error-amplifier stage and configured to generate an output voltage related to the first reference voltage by an amplification factor, and a feedback stage configured to generate the feedback voltage. A compensation stage is configured to implement a second feedback loop, and cause, in response to a variation of the output voltage, a corresponding variation of a first biasing voltage for the output amplifier stage. The compensation stage includes a coupling-capacitor element coupled between the output amplifier stage and a first internal node, and a driving module coupled between the first internal node, and the output amplifier stage and configured to generate a compensation voltage for driving the output amplifier stage.
