Abstract
An integrable circuit inductor (220) is formed from a patterned conductive material (110) that has a major portion completely encapsulated by a material (221, 223) that is substantially electrically non-conductive, and that has a magnetic response at the operating frequency of the inductor (220). Preferably, an amorphous ferrite material is used for encapsulation, which provides a closed magnetic flux path for the inductor (220) when processing a signal at its operating frequency.
