ABSTRACT:
The present invention provides integrated line drivers useable for driving data signals with high data rates wherein the area consumption of the line driver is minimized and wherein the influence of electrostatic discharge devices and process tolerances are minimized too. An example of an integrated line driver according to the invention comprises a first driver stage followed by a second driver stage, and a feedback unit forming with the second driver stage a control loop. The integrated line drivers are useable for driving data signals with high data rates wherein the area consumption of the line driver is minimized and wherein the influence of ESD devices and process tolerances are minimized. Advantageously, the integrated line driver according to the invention complies with chip design methodologies, where 10 or more routing metal layers are used.
