Abstract: A hybrid integrated circuit in a wafer level package for an implantable medical device includes one or more passive component windings formed, at least in part, along one or more routing layers of the package. The windings may be primary and secondary windings of a transformer, wherein all or part of a magnetic core thereof is embedded in a component layer of the wafer level package. If the core includes a part bonded to a surface of the package, that part of the core may be E-shaped with legs extending into the routing layers, and, in some cases, through the routing layers. Routing layers may be formed on both sides of the component layer to accommodate the transformer windings, in some instances.

Abstract: Various embodiments of a power source and method of forming such power source are disclosed. The power source can include a substrate and a cavity disposed in a first major surface of the substrate. The power source can also include radioactive material disposed within the cavity, where the radioactive material emits radiation particles; and particle converting material disposed within the cavity, where the particle converting material converts one or more radiation particles emitted by the radioactive material into light. The power source further includes a sealing layer disposed such that the particle converting material and the radioactive material are hermetically sealed within the cavity, and a photovoltaic device disposed adjacent the substrate. The photovoltaic device can convert at least a portion of the light emitted by the particle converting material that is incident upon an input surface of the photovoltaic device into electrical energy.
