Abstract
A technique to provide a compact integration of inductor-capacitor resonator a capacitor having a top plate and a bottom plate embedding a dielectric layer. The top and bottom plates are substantially parallel to each other. An inductor having a first end is coupled to the capacitor at the bottom plate. The inductor has N turns surrounding the bottom plate in a spiral geometry. The inductor is co-planar to one of the top and bottom plates and ends at a second end.
