Abstract

An integrated circuit package comprising an integrated circuit device and a voltage converter circuit both embedded within the package. The voltage converter circuit is configured to convert a standard supply voltage to an operating voltage as required by the integrated circuit device. Also, discrete embedded capacitors may be included to capacitively couple power and ground connections of the integrated circuit device and thus reduce voltage variations during operation of the integrated circuit device. The integrated circuit may package include one or more layers. One or more discrete components or integrated circuits are mounted to one or more layers within the package. Internal conductors on one or more of the layers are configured to connect the components forming the voltage converter circuit. Internal conductors also form connections to the integrated circuit device. The integrated circuit device and voltage converter circuit may be coated with an encapsulant for added protection. The integrated circuit package with embedded voltage converter may be manufactured with processes similar to those used for traditional integrated circuit packages and printed circuit board assemblies.
