Abstract:
A boosted differential driver comprising:a true differential output and a complement differential output; an output-high IOH current source for generating an IOH current for setting an output high voltage; an output-low IOL current source for generating an IOL current for setting an output low voltage; a first pull-down boost current sink; a second pull-down boost current sink; and a switch network that connects the IOH current source to the true differential output and connects the IOL current source to the complement differential output and connects the second pull-down boost current sink to the complement differential output when the true differential output is driven higher than then complement differential output, but connects the IOL current source to the true differential output and connects the IOH current source to the complement differential output and connects the first pull-down boost current sink to the true differential output when the true differential output is driven lower than the complement differential output, whereby the switch network switches the first and second pull-down boost current sinks and the IOH and IOL current sources among the true and complement differential outputs.
