Defected ground plane inductor

A semiconductor integrated circuit comprising:

• a semiconductor substrate;
• at least one insulating layer disposed on a first surface of said semiconductor substrate;
• a first spiral structure formed of a first conductive material layer disposed on said insulating layer, said first spiral structure having a terminal end at a location enclosed by one or more coils of said first spiral structure;
• a ground plane formed of a second conductive material and disposed on a second surface located on a side of said substrate opposed from said first surface, said ground plane defected so as to define a signal trace formed from a portion of said ground plane extending along an area of the second surface opposed from said spiral structure, said signal trace electrically isolated from a remainder of said ground plane by a gap in said second conductive material provided along a length of said signal trace between the signal trace and the portion of the ground plane, whereby said signal trace and said portion of said ground plane together define a coplanar waveguide;
• a conductive via extending through said at least one insulating layer, and through said semiconductor substrate, to form an electrical connection directly between said signal trace and said terminal end, said conductive via vertically aligned with said terminal end;
• and
• a plurality of electrical components disposed on said semiconductor substrate, wherein at least one of said electrical components is electrically connected to said signal trace.
