Abstract :
An analog front end IC for ADSL systems compliant with ANSI, ITU, and ETSI standards is presented. The IC contains all analog functions on one silicon die, including programmable gain amplifiers, highly linear continuous-time filters, 14-bit DAC and ADC for up to 1.1-MHz signal bandwidth, digitally controlled crystal oscillator, and a line driver capable of delivering +13 dBm to the line. 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. The high level of integration together with the low power consumption can be considered a benchmark for full-rate ADSL analog front end ICs
