  3. Abstract:
  4. In this paper a new low-voltage two-stage class-AB line driver for ADSL applications is presented. The new proposed line-driver consists of only two stages with a new method to control the quiescent current of the output stage. The low-voltage full-CMOS high-linear line driver shows -77 dB THD for a load as low as 20 ohms. The line driver has variable gain, attenuating the input signal from 0dB to -14dB with 2dB steps. The peak to peak differential output swing is 4.2-V from a 2.5-V Supply voltage in a 0.25um standard CMOS technology
