A quad-band GSM/GPRS/EDGE SoC in 65nm CMOS
2010
A quad-band 2.5G SoC integrates all the RF, DSP, ARM, audio and other baseband processing functions into a single 65nm CMOS die. The radio draws a battery current of 49mA in the RX-mode, and 86mA in the GMSK TX-mode. The low-IF receiver achieves a sensitivity of −110dBm at the antenna, corresponding to a noise figure of 2.4dB at the device input. The 8PSK ±400kHz modulation mask is −64.1/62.7dBc for high/low bands, with an RMS EVM of 2.45/1.95%.
