Abstract :
A low voltage, low power CMOS single chip baseband processor for CT2 and CT2+ cordless telephones is presented. The chip integrates a complete voiceband codec, a tone generator, a G721 AD-PCM coder/decoder, a Burst Mode Logic controller for CT2/CT2+ framings, and an I/Q baseband signal generator. It can be easily interfaced with standard microcontrollers through a parallel interface. It can operate from a 2.7 V minimum supply with operative and stand-by power consumptions of 35 mW and 25 μW, respectively. Maximum operative supply is 5.5 V. Chip area is 55.5 mm2 in a 0.8 μ N-well CMOS process
