Abstract :
A 0.6 um CMOS analog front end IC supporting ADSL central office and remote terminal (category I and II) modem applications is developed. The receive path contains a low-noise programmable gain amplifier, analog equalizer, antialiasing filter, and a 12 bit A/D converter. The transmit channel incorporates a 14 bit D/A converter and a low-pass filter. The IC consumes 525 mW on a 5 V supply.
