Abstract
A first voltage scaling power switch is coupled to a first power supply terminal for providing power to a first circuit portion, and a second voltage scaling power switch is coupled between the first power supply terminal providing power to a second circuit portion. A common power rail is coupled the first and second power input nodes during respective voltage scaling modes of the first and second circuit portions. A feedback circuit coupled to the common power rail provides a feedback signal to a control input of the first voltage scaling power switch to regulate a voltage provided by the first power switch, and to a control input of the second voltage scaling power switch to regulate a voltage provided by the second voltage scaling power switch.
