Abstract
An interdigitated capacitor having digits of varying width is disclosed. One embodiment of a capacitor includes a first plurality of conductive digits and a second plurality of conductive digits positioned in an interlocking manner with the first plurality of conductive digits, such that an interdigitated structure is formed. The first plurality of conductive digits and the second plurality of conductive digits collectively form a set of digits, where the width of a first digit in the set of digits is non-uniform with respect to a second digit in the set of digits.
