Abstract

PURPOSE:To reduce mismatching reflection by previously providing the resistor, whose resistance value can be varied in a step shape, to the terminal point of the fan-out wiring and by adjusting the value into the optimun resistance value depending upon the status of the wiring and the number of coupled logic circuits.
