Abstract
Multi-stage amplifiers, such as linear regulators or linear voltage regulators (e.g. low-dropout regulators) configured to provide a constant output voltage subject to load transients are presented. A multi-stage amplifier, having a differential amplification stage configured to provide a stage output voltage at an output node, based on a first input voltage and a second input voltage is presented. Furthermore, the multi-stage amplifier comprises a second amplification stage comprising an amplifier current source configured to provide an amplifier current; and an amplifier transistor arranged in series with the amplifier current source; wherein a gate of the amplifier transistor is coupled to the output node of the differential amplification stage. In addition, the multi-stage amplifier comprises a detection circuit.
