Abstract

An analog front-end IC with integrated line driver for an ADSL system is presented. The IC contains all analog functions including gain-controlled transmit- and receive-amplifiers, highly linear continuous-time low pass filters including on-chip automatic tuning, 14 bit ADC and DAC as well as a digitally controlled crystal oscillator. The IC has been fabricated in a mixed-signal 0.6 μm DPTM BiCMOS technology with a chip area of 29 mm² and a power consumption of only 800 mW, using 3.3 V supply for all blocks except 12 V supply for the line driver
