An analog front end for 2400b/s split-band full-duplex modems

A single chip analog front end for 1200 and 2400b/s modems that includes A/D and D/A converters, processor interfaces, 50 poles of filtering and equalization, tone generators, and a call progress detection filter, will be discribed. A 5μm CMOS implementation requires a die area of 6.5×6.37mm2.
