Driver with programmable power commensurate with data-rate

摘要

One embodiment of the invention includes a driver circuit. The driver circuit comprises an output transistor that is biased to provide an output signal in response to an input signal. The driver circuit also comprises at least one programmable variable resistor configured to provide a bias magnitude of the output transistor that sets a power of the driver circuit to be commensurate with a data-rate of the input signal.
