ABSTRACT:
Various embodiments provide a high speed serial transmitter that utilizes a current-mode driver comprising a main driver and a de-emphasis driver. The de-emphasis driver includes a first driver circuit and a complementary second driver circuit that is operably coupled with the first driver circuit. Collectively, the first driver circuit and its complementary second driver circuit work in concert to compensate to correct the lower output common-mode level in de-emphasized bits.
