Abstract :
A 0.25µm 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 0.25µm triple-well CMOS technology, with a chip area of 25mm2, and a power consumption of only 300mW using 2.5V supply.
