Abstract :
This paper describes a four-channel ADSL2+ analog front-end (AFE) targeted at a central office application, with a power consumption of 75 mW per channel. The design is implemented using a modern 0.13-μm CMOS process. The AFE consists of a 14-bit ADC and DAC, a very low-noise high-linearity automatic gain control (AGC), analog filter blocks, and digital decimation and interpolation filter stages. The design has been optimized to achieve the lowest possible power consumption, high performance, and cost efficiency.
