A 1.544-Mb/s CMOS line driver for a 22.8- Omega load

A CMOS line driver for high-speed data communication according to the T1 and CEPT recommendations is presented. The differential output swing is 7.2 V/sub pp/ on a load of 22.8 Omega from a single 5-V supply. A novel quiescent current control scheme is used. The driver occupies an area of 6.5 mm/sup 2/ using a 2- mu m p-well CMOS technology.<
