摘要： A biasing circuit includes a differential communication line comprising a first signal line and a second signal line. The biasing circuit further includes a first current source coupled between a power supply and the first signal line. The biasing circuit further includes a first high-precision voltage reference coupled to the first current source, wherein the first high-precision voltage reference outputs a reference voltage that drives a current produced by the first current source. The biasing circuit further includes a second current source coupled to the second signal line and a system ground, wherein the second current source is driven by a voltage supplied by the power supply.
