Abstract
A semiconductor package includes a package substrate and an integrated circuit. The package substrate has a first surface. The integrated circuit couples electrically to the first surface of the package substrate. The integrated circuit and the package substrate together form the semiconductor package. The semiconductor package also includes a first inductance circuit and a second inductance circuit, both formed within the semiconductor package. The first and second inductance circuits couple to each other in parallel. The first and second inductance circuits have substantially symmetrical geometric characteristics.
Claims2
A semiconductor package comprising:
- a package substrate having a first surface;
- an integrated circuit electrically coupled to the first surface of the package substrate, the integrated circuit and the package substrate together forming the semiconductor package;
- and
- a first inductance circuit formed within the semiconductor package;
- and
- a second inductance circuit formed within the semiconductor package,
- wherein the first inductance circuit is coupled in parallel to the second inductance circuit, and
- wherein the first and second inductance circuits have substantially symmetrical geometric characteristics.
A semiconductor package comprising:
- a package substrate having a first surface;
- an integrated circuit electrically connected to said first surface of said package substrate, said integrated circuit and said package substrate together forming said semiconductor package, the integrated circuit and package substrate including frequency synthesizer circuitry;
- and
- at least one inductance circuit formed entirely within said semiconductor package and formed at least partially between said integrated circuit and said package substrate, the inductance circuit at least in part determining an output frequency for the frequency synthesizer circuitry;
- wherein said frequency synthesizer circuitry has an output frequency selectably operable within a plurality of bands, and wherein said at least one inductance circuit forms part of a controlled oscillator circuit within said frequency synthesizer circuitry, the output frequency being dependent upon the controlled oscillator circuit.
