1. A multi-segment capacitor fabricated on a semiconductor substrate, comprising:

  • multiple banks of capacitor segments, the capacitor segments within each bank being connected in parallel, each capacitor segment including a plurality of capacitor elements, each capacitor element including two sets of electrically insulated and spatially interleaved parallel conductive fingers having a longitudinal axis;

    wherein the conductive fingers of a first capacitor element of at least one capacitor segment have a longitudinal axis that is not parallel to the longitudinal axis of the conductive fingers of a second capacitor element of the same capacitor segment;

    wherein the multiple banks of capacitor segments are connected in accordance with a predefined connection scheme; and

    wherein a first metal line is selectively connected to a capacitor segment within a first bank of capacitor segments and a second metal line is selectively connected to a capacitor segment within a second bank of capacitor segments.
