Abstract
Method and apparatus for voltage biasing a bus line are disclosed. In one embodiment, a terminator voltage biases a differential data line having a first bus line and a second bus line. The terminator, includes a resistor network, a biasing control circuit, and a controllable biasing circuit. The resistor network is coupled to the differential data line and has a network impedance substantially equal to the characteristic bus impedance of the differential data line. The controllable biasing circuit is coupled to the resistor network and is configured to generate (i) a first control signal and (ii) a second control signal. The controllable biasing circuit is coupled to the resistor network and to the biasing control circuit. The controllable biasing circuit is configured to generate a differential biasing voltage between the first bus line and the second bus line that is based on the first control signal and the second control signal.
