Abstract
An integrated circuit (IC) can include multiple power domains that are served by a common power source. In an example, a first IC power rail can be coupled to the source and a first consumer circuit. A second IC power rail can be coupled to a second consumer circuit. The second IC power rail can receive a filtered power signal from an isolation module that is coupled between the first and second power rails. In an example, an isolation module includes an integrated inductor and a capacitor (e.g., a land-side capacitor). The integrated inductor can optionally include multiple spaced apart conductive layers that are electrically coupled. The integrated inductor can optionally include a series of conductive traces and plated through holes or vias that together provide a current path with multiple turns.
