ISSCC 2010 / SESSION 10 / DC - DC POWER CONVERSION / 10 . 8 10 . 8 A 32 nm Fully Integrated Reconfigurable Switched - Capacitor DC - DC Converter Delivering 0 . 55 W / mm

With the rising integration levels used to increase digital processing performance, there is a clear need for multiple independent on-chip supplies in order to support per-IP or block power management. Simply adding multiple off-chip DCDC converters is not only difficult due to supply impedance concerns, but also adds cost to the platform by increasing motherboard size and package complexity. There is therefore a strong motivation to integrate voltage conversion blocks on the silicon chip.
