Abstract
The present invention involves a geometric structure for a pair of matched capacitors for use in an integrated circuit device. Each of the matched capacitors are composed of at least one of a unit capacitor and one or more subcapacitors arranged in abutting relationship. Each subcapacitor includes a tab projecting outwardly and an opening of similar size projecting inwardly. The tab is arranged to abut against the side of a unit capacitor or another subcapacitor. The tabs and openings are sized so that the area to peripheral length ratios of the matched capacitors are identical.
