traditionally , complementary metal oxide semiconductor and bipolar transistors have been separately employed in low voltage differential signal drivers . here , a hybridized lvds driver is provided with an input stage that uses cmos transistors and output stages that use bipolar transistors . as a result of this hybridization , the lvds driver has superior functional characteristics compared to conventional lvds drivers as well as being able to function with a supply range between about 1 . 8v and 3 . 3v .
