Abstract:
A stacked LC resonator includes a parallel-plate capacitor, a dielectric layer and a spiral inductor. The parallel-plate capacitor has a first metal layer, a second metal layer opposed to the first metal layer and a middle dielectric layer formed between the first and second metal layers. The dielectric layer is formed on the second metal layer of the parallel-plate capacitor. The spiral inductor is formed on the dielectric layer and electrically connected with the first and second metal layers of the parallel-plate capacitor.
