Titel
A low-voltage low-power 0.25 µm CMOS ADSL analog front-end IC
Abstract
A 0.12 µm 2.5V CMOS analog front-end IC 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 filtering including on-chip automatic tuning. 8.8Ms/s ADC and DAC as well as a crystal driver and a DAC-controlled VCO. The IC has been realized in a mixed-signal 0.25 µm triple-well CMOS technology, with a chip area of 25 mm², and a power consumption of only 300mW using 2.5V supply.
