Summary: 
A general-purpose multi-Gbps LVDS driver is presented with a new distortion-free level conversion scheme. For high-speed transmission, a dynamic pre-emphasis scheme is also proposed with overdriving current effectively distributed in time. The proposed LVDS driver achieves supply-insensitive duty preservation with a reduction of switching noise by 50-percent.
