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.

Differential filters for removing both normal-mode and common-mode noises are provided. A first-order differential low pass filter is composed of a first resistor connected between a first input terminal and a first output terminal, a second resistor having the same resistance value as the first resistor and connected between a second input terminal and a second output terminal, a first capacitor connected between the first output terminal and a reference potential, a second capacitor having the same capacitance value as the first capacitor and connected between the second output terminal and the reference potential, and a third capacitor connected between the first output terminal and the second output terminal.
