Systems and methods for providing capacitor structures in an integrated circuit

Abstract:

A capacitor includes a first metal layer over a substrate, a second metal layer over the first metal layer, and first and second cells. Each cell is electrically coupled to first and second buses. Each cell includes first plurality and second plurality of fingers in the first metal layer, and third plurality and fourth plurality of fingers in the second metal layer. The first plurality of fingers extend in a first direction parallel to a top surface of the substrate and are electrically coupled to the first bus. The second plurality of fingers extend in the first direction and are electrically coupled to the second bus. The third plurality of fingers extend in a second direction parallel to the top surface of the substrate and are electrically coupled to the first bus. The second direction is different from the first direction. The fourth plurality of fingers extend in the second direction and are electrically coupled to the second bus.
