초록 ▼

A fingered capacitor in an integrated circuit. A first capacitor element is formed in a first layer of an integrated circuit (IC) die. The first capacitor element includes a positive plate and a negative plate. Each of the positive and negative plates of the first capacitor element has a plurality of fingers interdigitated with the fingers of the other of the positive and negative plates of the first capacitor element. The fingers are separated by a dielectric. The interdigitated fingers cooperate to generate fringe capacitance between neighboring fingers. A plurality of capacitor elements having interdigitated fingers can be provided in adjacent layers of the IC die.
