Abstract
An inductor cell for vertical power delivery includes a first plate, a second plate, a power conductor, an inductor core, and a ground conductor. The power conductor extends between the first plate and the second plate in a vertical direction. The inductor core extends between the first plate and the second plate in the vertical direction. The ground conductor extends between the first plate and the second plate in the vertical direction. The power conductor is configured to deliver power between the first plate and the second plate along the vertical direction. The inductor cell is configured as an inductor in a power delivery path.
