  • On-chip calibrated source termination for voltage mode driver and method of calibration thereof
    Patent number: 7119611
    Abstract: On-chip calibrated source termination for voltage mode driver. An amplifier is disclosed having an internal amplifier with a first output and a second output, the first output interfaced to a non-inverting input through an interface. The second output is coupled to the first output through a series resistance element. The output impedance of the amplifier is determined by the ratio of the current drive of the first and second outputs. The voltage on said second output being a function of said interface and the current input to said internal amplifier.

  • Output driver for high speed Ethernet transceiver
    Patent number: 6665347
    Abstract: Output driver for high speed Ethernet transceiver. A transmission line driver is disclosed for driving a transmission line in a first operating mode and in a second operating mode. The first and second operating modes operate substantially exclusive of each other. A current driver is provided for driving the transmission line in the first operating mode from a first data generator and at a first output voltage. A voltage driver is provided for driving the transmission line in the second operating mode from a second data generator at a second output voltage through a load, such that the current driver and the voltage driver operate independent of each other.
