Abstract
A single/Multi-phase PMIC built on silicon substrate with coil layers processed on top of the PMIC layers' is provided. The integrated coil is in a spiral form, with a gap at the center of the coil, making additional metal routing not required. The integrated coil has connection pads located in the center gap of the spiral form, limiting the overall inductor resistance to the device only. The on-die inductor may have a magnetic core wrapping the windings. The spiral form may be implemented in a circular design, or a racetrack (elongated spiral) design. The coil layers may be implemented as multiple coil layers or as a single coil layer, connected in parallel (with the same I/O pads), reducing the resistance and maintaining the inductance.
