Zusammenfassung:In one embodiment, an apparatus includes a first reference voltage coupled to a first metal layer and a second reference voltage coupled to a second metal layer. A first finger type in the plurality of fingers is coupled to the first metal layer at a first area and coupled to the first metal layer and the second metal layer at a second area. A second finger type in the plurality of fingers is coupled to the second metal layer at the first area and coupled to the first metal layer and the second metal layer at the second area. Also, the first finger type and the second finger type alternately positioned next to each other.
