Abstract
Abstract The disclosure relates to integrated circuit resistors and matched resistor pairs wherein each resistor is split into plural segments, each segment having a separate field plate thereover, each segment having the field plate associated therewith connected to the non-common node thereof. In the case of the matched resistor pair, the interconnections between the segment of each resistor overlap. The segments are preferably substantially rectangular in shape with the major axes of all segments parallel to each other.
