Abstract :
This paper presents a 3G CDMA2000 1X cellular-baseband chip, with GSM/AMPS/GPS/Bluetooth/multimedia capabilities, which uses an embedded ARM and two DSP processors. It is implemented with 27 M transistors in 46.9 mm2 using a 130 nm dual-VT low-power CMOS process and achieves a three to four times standby-time improvement by the selective use of footswitches.
