An embodiment of a method includes generating a regulated output signal from a regulated intermediate signal in response to a reference signal and the regulated output signal, and generating the regulated intermediate signal from an input signal in response to the regulated output signal and the regulated intermediate signal. By generating one regulated signal (e.g., a regulated output voltage) from another regulated signal (e.g., a regulated intermediate voltage), one may significantly reduce the magnitude of the ripple component of the one regulated signal as compared to a conventional regulation technique. Furthermore, by generating the regulated intermediate signal in response to the regulated output signal, one may significantly increase the efficiency of the regulation as compared to conventional signal regulation.
