  • Precision on-chip transmission line termination
    Patent number: 6605958
    Abstract: Methods and apparatus for providing precision on-chip termination of transmission lines are provided which enable the termination of transmission lines using on-chip resistors configured into networks, which have resistances related to the resistance of an external reference resistor. The external reference resistor is used to configure an on-chip reference resistor network so that it has a resistance related to the resistance of the external reference resistor. Termination resistor networks are then configured so that their resistances bear a predetermined relationship to the resistance of the on-chip reference resistor network. In one embodiment the resistance of each of the termination resistor networks is substantially the same as the characteristic impedances of each of the transmission lines.
