A semiconductor device has a first coil structure formed over the substrate. A second coil structure is formed over the substrate adjacent to the first coil structure. A third coil structure is formed over the substrate adjacent to the second coil structure. The first and second coil structures are coupled by mutual inductance, and the second and third coil structures are coupled by mutual inductance. The first, second, and third coil structures each have a height greater than a skin current depth of the coil structure defined as a depth which current reduces to 1/(complex permittivity) of a surface current value. A thin film capacitor is formed within the semiconductor device by a first metal plate, dielectric layer over the first metal plate, and second and third electrically isolated metal plates opposite the first metal plate. The terminals are located on the same side of the capacitor. |
