Abstract:
1. A multiple layer inductor implemented on a substrate having a plurality of layers, each layer having a top surface and a bottom surface, said multiple layer inductor comprising: a first spiral conductive pattern disposed on a top surface of a first of the plurality of layers; a second spiral conductive pattern disposed on a top surface of a second of the plurality of layers; a continuing interconnection coupled to said first and second spiral conductive patterns; an interface having a first terminal and a second terminal disposed on said top surface of said first of the plurality of layers, wherein said first terminal is coupled to said first spiral conductive pattern and second terminal is coupled to said second spiral conductive pattern; a first conductive shield pattern having a first common voltage potential and disposed on a top surface of a third of the plurality of layers, wherein said third of the plurality of layers is adjacent to said second of the plurality of layers; and a second conductive shield pattern having a second common voltage potential and disposed on a top surface of a fourth of the plurality of layers, wherein said fourth of the plurality of layers is adjacent to said top surface of said first of the plurality of layers; first and second conductive side shield patterns disposed on respective perimeters of said first and second layers.
