A bandgap voltage generator includes an output node for providing an output voltage, a current mirror coupled between the output node and a voltage reference, and a biasing transistor coupled to the output node. A feedback line includes a feedback transistor coupled to the output node. A current generator biases the feedback transistor by injecting a current into a bias node of the feedback line. A capacitor is coupled between the bias node and the voltage reference. The feedback line includes a circuit coupled between the bias node and the feedback transistor for causing a current to flow through the feedback transistor, and for increasing a resistance of a portion of the feedback line in parallel to the capacitor.
