Abstract
An electronic device has an electronic device includes a substrate and a first dielectric layer over the substrate. The electronic device also includes a first metal layer on the first dielectric layer, the first metal layer including a first plate and a second dielectric layer over the first dielectric layer and the first metal layer. Additionally, the electronic device includes a second metal layer on the second dielectric layer. The second metal layer includes a second plate spaced apart from the first plate and a winding around the second plate.
