Abstract
A switching power supply in an integrated circuit, an integrated circuit comprising a switching power supply, and a method of assembling a switching power supply in an integrated circuit are disclosed. In one embodiment, the invention provides a three-dimensional switching power supply in an integrated circuit comprising a device layer. The switching power supply comprises three distinct strata arranged in series with the device layer, the three distinct strata including a switching layer including switching circuits, a capacitor layer including banks of capacitors, and an inductor layer including inductors. This switching power supply further comprises a multitude of connectors electrically and mechanically connecting together the device layer, the switching layer, the capacitor layer, and the inductor layer. The switching circuits, the capacitors and the inductors form a switching power supply for supplying power to the device layer.
