Abstract
A multi-segment capacitor fabricated on a semiconductor substrate includes M×N capacitor segments arranged in a matrix of M rows and N columns. Each capacitor segment includes two groups of conductive fingers preferably made of metal wires. The metal wire fingers are distributed within multiple metal layers in such a manner that two neighboring parallel metal wire fingers within a particular metal layer are electrically insulated and connected to different terminals of the capacitor. Further, at least the longitudinal axes of the parallel metal wire fingers within two different metal layers are not parallel to each other within the same capacitor segment.
