Abstract
A self-biased differential transmitter is provided. The transmitter may include a differential output driver powered by a supply voltage provided by a differential signal receiver. The output driver may include a bias voltage generator to generate bias voltages to enable one or more transistors in the output driver to operate with differential signals that are beyond the safe operating voltage range of transistors included within the differential transmitter.
