Abstract
A power-supply filter that is built into an integrated circuit package is disclosed. An LC, RC, or RLC filter is built into the integrated circuit's chip carrier module and connected so as to filter the power supply entering the integrated circuit. By manufacturing the filter as part of the integrated circuit package, a chip manufacturer can eliminate the need for application-level developers to provide an external filtering network in the deployment of the integrated circuit in an application circuit.
Claims23
An integrated circuit package comprising:
- an integrated circuit having a power supply terminal;
- a substrate;
- and
- a filter having an output connected to the power supply terminal, wherein the filter includes filter components and the filter components are mounted to the substrate.
A circuit comprising:
- an integrated circuit package, the integrated circuit package including:
- a first power supply terminal;
- an integrated circuit having a second power supply terminal;
- a substrate;
- and
- a filter having a filter input terminal and a filter output terminal, wherein the filter input terminal is connected to the first power supply terminal, the filter output terminal is connected to the second power supply terminal, the filter includes filter components, and the filter components are mounted to the substrate.
