Abstract :
An analog-front-end design including the power-management circuits to achieve an SoC ADSL CPE modem solution is presented. The integrated AFE with less than 2nV/√Hz input referred noise, dynamically adaptive hybrid and combination of the analog and digital filtering provides a single-chip solution.
