A technique for compensating a characteristic, such as a resistance, of at least one circuit includes selectively incrementing a characteristic of a dummy circuit and comparing it with a characteristic of an external reference to generate a reference code. A previous reference code is stored and subsequently compared with a present reference code. It is ensured that the present reference code differs by no more than a predetermined amount from the stored previous reference code by ceasing the incrementing or decrementing of the characteristic of the dummy circuit and utilizing the present reference code to compensate the characteristic of the at least one circuit.
