Abstract
Various embodiments relate to an integrated circuit including a transistor device having input and output terminals, and an inductor-capacitor (LC) circuit coupled to one of the terminals of the transistor device. The LC circuit includes a capacitor having a top plate and a bottom plate, a inductor having a coil structure, and a connector configured to couple the inductor and an interior portion the top plate of the capacitor. The inductor at least partially overlaps the capacitor.
