Abstract
A method for calibrating a resistance value comprises the steps of measuring a value of a reference capacitor, and adjusting a variable resistor based on the measured value of the reference capacitor. The method may more specifically comprise the steps of directing a constant current through the reference capacitor during a reference time interval; after the reference time interval, directing the constant current through the variable resistor; and varying the variable resistor value progressively by varying a control signal until a voltage of the variable resistor reaches a voltage of the reference capacitor.
