A circuit arrangement (e.g., an integrated circuit) generates a second or higher order compensation voltage to compensate for variations in operation parameters (e.g., temperature and process variations). In one aspect, the compensation voltage is applied to a MOS resistor to compensate for mobility variations of the MOS resistor by maintaining a stable equivalent resistance. The compensated MOS resistor can provide a relatively stable resistance for a variety of analog circuit applications, such as a current reference.
