Title: Resistor compensation apparatus

Abstract: A compensation apparatus maintains an effective resistance of one or more resistors in a circuit by associating an adjustable resistor circuit to each resistor. The compensation apparatus compares the resistance of a resistor in the circuit with the resistance of a reference resistor. When the resistance of the resistor in the circuit falls outside of a desired range, the compensation apparatus adjusts the resistance of the adjustable resistor to adjust the effective resistance of the resistor and adjustable resistor combination.
