An impedance matching arrangement, including an adaptive circuit. The adaptive circuit includes a first adaptive portion allowing impedance matching according to a predetermined first weighting scheme, and a second adaptive portion allowing impedance matching according to a predetermined second weighting scheme which differs from the first weighting scheme. The first adaptive portion is operable substantially during initialization times, and the second adaptive portion is operable substantially outside initialization times. The first adaptive portion may have a binary weighting scheme, and the second adaptive portion may have a linear weighting scheme. Finally, the adaptive 1 circuit is provided as a portion of an integrated circuit (IC) die.
