ABSTRACT:
A CMOS driver circuit which differentially drives a pair of transmission lines at a first terminal in response to a signal on the CMOS driver circuit's input terminal for reception of said signal at a second terminal is provided. The driver circuit has two pairs of drive transistors. Each drive transistor has first and second source/drains and a gate. Each drive transistor pair is connected to one of said transmission line pair, and has a NMOS transistor and a PMOS transistor.
