Abstract
A power supply includes a source signal generating circuit, an output stage, and a feedback stage. The power supply further includes a replica stage configured to replicate a response of the output stage to the source signal, and an output regulator coupling the replica stage to the output stage, configured to adjust a feedback signal to the source signal generating circuit by shunting the feedback stage when a loaded output stage response does not match a response of the replica stage to the source signal.
