A capacitor includes a cell array including a plurality of cells and a fine tuning cell electrically coupled to the cell array by a first bus and a second bus. Each cell of the cell array includes a first number of fingers electrically coupled to the first and second bus, and a second number of fingers electrically coupled to the first and second bus. The fine tuning cell includes a third number of fingers electrically coupled to the first and second bus, and a fourth number of fingers electrically coupled to the first and second bus. The directional alignment of the first and second number of fingers is generally perpendicular, the directional alignment of the third and fourth number of fingers is generally perpendicular, and the second number of fingers is different than the fourth number of fingers.
