Abstract
The present invention provides a Differential Signaling line driver including a pre-emphasis circuit, which boosts the output drive current without any delay whenever there is a transition in the input signal to the driver, using the input signal itself to provide the pre-emphasis through a current steering circuit that switches the direction of drive currents to provide a differential output signal. A delayed signal is then used to disable the pre-emphasis after a short period.
