A CMOS line driver for ADSL central office applications.

A CMOS line driver for ADSL central office applications.

An ADSL central office (CO) line driver utilizing a single 6-V supply is described. The line driver output produces a 20-Vppd signal to deliver a 40-Vppd swing to a 100-Ω line. The adoption of an active termination, a dynamic supply control circuit technique, and deep n-well devices at the output st...
