Multielement magnetic probe using commercial chip inductors
نویسندگان
چکیده
A 60-element magnetic probe array has been constructed using miniature commercial chip inductors. The array consists of twenty clusters of three coils each mounted on a linear fixture. The coils are oriented in orthogonal directions to yield three-dimensional information. The array has been used to investigate magnetic properties of spheromaks. © 2004 American Institute of Physics.

Development of Three-Dimensional Inductors Using Plastic Deformation Magnetic Assembly (PDMA)
On-chip inductors are critical for enabling portable power-efficient wireless communication systems. Existing on-chip spiral inductors based on conventional planar integrated-circuit fabrication technology suffer from substrate loss and parasitics, and have relatively large footprints. In this paper, we discuss the development of two types of on-chip three-dimensional (3-D) inductors—a vertical...
متن کاملMicromachined planar inductors on silicon wafers for MEMS applications
This paper describes three micromachined planar inductors (a spiral type, a solenoid type, and a toroidal meander type) with electroplated nickel–iron permalloy cores which have been realized on a silicon wafer using micromachining techniques. The electrical properties among the fabricated inductors are compared and the related fabrication issues are discussed, with emphasis on the low-temperat...
متن کاملOn-chip inductors with self-rolled-up SiNx nanomembrane tubes: a novel design platform for extreme miniaturization.
Inductors are essential components of radio frequency integrated circuits (RFICs). While the active devices in RF systems downscale steadily, inductors have not been able to keep up with the pace of continual miniaturization because of the trade-off between size and performance as well as fabrication complexity. Strain-induced self-rolled-up nanotechnology allows the formation of three-dimensio...
متن کاملThrough-Silicon-Via Inductor based DC-DC Converters: The Marriage of the Princess and the Dragon
There has been a tremendous research effort in recent years to move DC-DC converters on chip for enhanced performance. However, a major limiting factor to implement on-chip inductive DC-DC converters is the large area overhead induced by spiral inductors. Towards this, we propose to use through-silicon-vias (TSVs), a critical enabling technique in three-dimensional (3D) integrated systems, to i...
متن کاملChip-level integration of RF MEMS on-chip inductors using UV-LIGA technique
This paper presents a chip-level integration of radio-frequency (RF) microelectromechanical systems (MEMS) air-suspended circular spiral on-chip inductors onto MOSIS RF circuit chips of LNA and VCO using a multi-layer UV-LIGA technique including SU-8 UV lithography and copper electroplating. A high frequency simulation package, HFSS, was used to determine the layout of MEMS on-chip inductors wi...
