ABSTRACT:
An integrated circuit (IC) includes a substrate having a top semiconductor surface and a bottom surface, and integrated circuitry including an analog subcircuit and at least one digital subcircuit formed on the top semiconductor surface. A plurality of through substrate vias (TSVs) extend through the substrate. At least one integrated Faraday shield includes a top and a bottom electrically conducting member that are coupled by the TSVs which surround the analog subcircuit and/or the digital subcircuit. At least one voltage regulator supplies a regulated power supply voltage that is coupled to the integrated Faraday shield that surrounds the analog subcircuit.
