ABSTRACT:
A variable impedance sense (VIS) circuit (400) can detect a drift in the impedance of variable impedance circuits due to changes in operating conditions. Adjustments to binary impedance setting codes are made in response to a detected drift only when such changes do not increase a worst case variation from a target impedance. Adjustments can also be made in response to a detected input offset polarity.
