Abstract
Predriver equalization is described. A predriver includes a predriver equalizer to provide equalization on outputs of predrivers. The predriver equalization causes the predrivers to drive the output driver and a preemphasis driver with signals equalized to reduce common mode noise on the output signal. The predrivers can be implemented as complementary semi-differential driver circuits or as complementary logic circuits with weak pull-downs. The driver complexity can be reduced to the use of a semi-differential driver with the use of the predriver equalization.
