Zusammenfassung:An integrated circuit (IC) includes a package-integrated Faraday cage assembly to reduce the level of electromagnetic radiation emanating from the IC during operation. The IC uses a number of appropriately spaced leads on the IC package to form part of a Faraday cage surrounding a semiconductor chip within the IC. In one approach, the selected leads are coupled by a conductive member to a conductive cover plate of the IC package that forms an upper boundary of the Faraday cage. When the IC is installed in an external circuit, some or all of the selected leads are coupled together outside of the IC package (e.g., to an electrical ground) to form the lower boundary of the Faraday cage.
