Abstract

A metal capacitor includes a plurality of interconnect segments. A first plurality of L-shaped fingers is driven to a first voltage level by a first interconnect segment. A second plurality of L-shaped fingers is driven to a second voltage level by a second interconnect segment. Each of the L-shaped fingers from a set of the first plurality of L-shaped fingers is adjacent to at least one of the L-shaped fingers from a set of the second plurality of L-shaped fingers.
