Planar Miniature Inductors And Transformers

US Patent:
6683522, Jan 27, 2004
Filed:
May 21, 2001
Appl. No.:
09/861736
Inventors:
Joseph G. Walsh - Brookline MA
Assignee:
Milli Sensor Systems Actuators, Inc. - West Newton MA
International Classification:
H01F 3820
US Classification:
336175, 336176, 336174, 296021
Abstract:
The planarization of inductive components by reducing standard coiled designs to single turn, open ended designs from which the required parameters are obtained by scaling the length. Single turn designs having magnetic material encircling the conductors along their full length enable the thinnest form. The single turn, open ended form also enables the inductive component to be routed according to any shape in the plane or on any conformal surface. The single turn inductors do not need to coil hence there is no overlap necessary in the plane. The planar form allows integration of inductive components with integrated circuits. These inductive components can be embedded in other materials. They can also be fabricated directly onto parts.

Fabrication Approaches For The Formation Of Planar Inductors And Transformers

US Patent:
6990725, Jan 31, 2006
Filed:
Oct 4, 2002
Appl. No.:
10/265170
Inventors:
Mark D. Fontanella - Wellesley MA, US
Paul Greiff - Wayland MA, US
Donato Cardarelli - Medfield MA, US
Joseph G. Walsh - Brookline MA, US
International Classification:
H01F 7/06
US Classification:
296021, 29604, 29605, 29606, 29829, 156 8911, 156 8912, 156250, 257531, 336176, 336200, 336229, 438238, 438381, 438788, 438792
Abstract:
This invention relates to the fabrication of planar inductive components whereby the design in cross-section describes a conductor surrounded by magnetic material along the length of the conductor; an electrical insulator is placed between the conductor and the magnetic material. Cases also apply where more than one independent conductor is used. The planar form allows integration of inductive components with integrated circuits. These inductive components can be embedded in other materials. They can also be fabricated directly onto parts.
