ABSTRACT:
An integrated circuit resistor array suitable for use as resistors included in a high performance analog integrated circuit is provided. A plurality of resistor stripes are collectively arranged in a region on a substrate. The resistor stripes are made of the same material and designed to have the same cross-sectional area. The resistor stripes are electrically connected through first metal layer conductors. Second metal layer conductors connect the stripes to external circuits. Different resistors have matched voltage dependencies.
