Symmetric Inducting Device For An Integrated Circuit Having A Ground Shield

View page
US Patent:
6635949, Oct 21, 2003
Filed:
Jan 4, 2002
Appl. No.:
10/039200
Inventors:
Rex Everett Lowther - Palm Bay FL
William R. Young - Palm Bay FL
Assignee:
Intersil Americas Inc. - Milpitas CA
International Classification:
H01L 2900
US Classification:
257531, 257277, 257351, 257495, 257528, 336223
Abstract:
The present invention relates to integrated circuits having symmetric inducting devices with a ground shield. In one embodiment, a symmetric inducting device for an integrated circuit comprises a substrate, a main metal layer and a shield. The substrate has a working surface. The main metal layer has at least one pair of current path regions. Each of the current path region pairs is formed in generally a regular polygonal shape that is generally symmetric about a plane of symmetry that is perpendicular to the working surface of the substrate. The shield is patterned into segments that are generally symmetric about the plane of symmetry. Medial portions of at least some segments of the shield are formed generally perpendicular to the plane of symmetry as the medial portions cross the plane of symmetry.

Inductor Device With Patterned Ground Shield And Ribbing

US Patent:
6756656, Jun 29, 2004
Filed:
Jul 11, 2002
Appl. No.:
10/194496
Inventors:
Rex Everett Lowther - Palm Bay FL
Assignee:
GlobespanVirata Incorporated - Red Bank NJ
International Classification:
H01L 2900
US Classification:
257531, 257528
Abstract:
Inducting devices having a patterned ground shield with ribbing in an integrated circuit. In one embodiment, an inducting device comprises conductive turns to conduct current, a shield layer and a plurality of ribs. The shield layer is formed a select distance from the conductive turns. The shield layer is patterned into sections of shield to prevent eddy currents. The plurality of ribs are formed from a conductive layer that is positioned between the conductive turns and shield layer. Each rib is electrically coupled to a single associated section of shield. Moreover, each rib is more conductive than its associated section of shield to provide a less resistive current path than its associated section of shield.

US Patent:
6775807, Aug 10, 2004
Filed:
Aug 19, 2002
Appl. No.:
10/224170
Inventors:
Rex Lowther - Palm Bay FL
Yiqun Lin - Melbourne FL
Assignee:
Intersil Americas Inc. - Milpitas CA
International Classification:
G06F 1750
US Classification:
716 1, 716 18, 703 2
Abstract:
A method of determining electrical parameters of inductive elements includes a novel technique of inverting an impedance matrix representative of said inductive circuit element. The method reduces model simulation time by a factor of 3000. In one embodiment, simulation time of a device model was reduced from 1 hour to less than 3 seconds. The method is suitable for use with circuit element modeling tools, circuit simulation environments, and antenna modeling systems. The method may be applied to inductors, transformers, antennas, etc.

US Patent:
6803849, Oct 12, 2004
Filed:
Oct 31, 2002
Appl. No.:
10/284624
Inventors:
Rex Lowther - Palm Bay FL
Assignee:
Intersil Americas Inc. - Irvine CA
International Classification:
H01F 500
US Classification:
336200, 336223, 336232, 29605
Abstract:
An integrated circuit having an inducting device with a symmetric inductor. The inducting device comprises a first and second inductor. The first inductor is formed in a first conductive layer and is approximately symmetric about a plane of symmetry. The second inductor is formed in a second conductive layer that is at a select vertical distance from the first conductive layer. The second inductor is further approximately laterally aligned with the first inductor.

Appl. No.:
10/645709
Inventors:
Rex Everett Lowther - Palm Bay FL, US
William R. Young - Palm Bay FL, US
Assignee:
Globespan Virata Incorporated - Red Bank NJ
International Classification:
H01L021/8238
US Classification:
438202, 438214, 438254
Abstract:
The present invention relates to integrated circuits having symmetric inducting devices with a ground shield. In one embodiment, a symmetric inducting device for an integrated circuit comprises a substrate, a main metal layer and a shield. The substrate has a working surface. The main metal layer has at least one pair of current path regions. Each of the current path region pairs is formed in generally a regular polygonal shape that is generally symmetric about a plane of symmetry that is perpendicular to the working surface of the substrate. The shield is patterned into segments that are generally symmetric about the plane of symmetry. Medial portions of at least some segments of the shield are formed generally perpendicular to the plane of symmetry as the medial portions cross the plane of symmetry.
