  • Precompensated driver with constant impedance
    Publication number: 20050258870
    Abstract: An apparatus and method is disclosed for transmitting signals over a signal conductor using a precompensated driver that does not use a current source, and which drives the signal conductor with an impedance similar to the characteristic impedance of the signal conductor. Since no current source is used, the precompensated driver can operate at very low supply voltage.

  • METHOD AND APPARATUS FOR IMPLEMENTING POWER CONTROL IN MULTI-VOLTAGE I/O CIRCUITS
    Publication number: 20050156623
    Abstract: A method and apparatus are provided for implementing power control in multi-voltage input/output (I/O) circuits. First current biasing devices are provided for creating a first constant bias current. Second current biasing devices are provided for creating a second bias current. The second current biasing devices are activated at a first voltage and are deactivated at a second voltage. The first voltage is less than the second voltage.
