Abstract:
Multi-stage amplifiers, such as linear regulators, provide a constant output voltage subject to load transients. The multi-stage amplifier includes a first amplification stage which activates or deactivates a first output stage in response to an input voltage at an input node. The first output stage sources a current at an output node of the multi-stage amplifier from a high potential, when activated. Furthermore, the multi-stage amplifier has a second amplification stage to activate or to deactivate a second output stage in response to the input voltage at the input node. The second output stage sinks a current at the output node of the multi-stage amplifier to a low potential, when activated. The first amplification stage and the second amplification stage activate the first output stage and the second output stage in a mutually exclusive manner.
