Abstract: This work provides a dual-mode transceiver chipset for wireless body area network (WBAN). The modulation schemes include both MT-CDMA and OFDM. A phase-frequency tunable clock generator (PFTCG) is designed with frequency and phase tuning capability on the fly. A rotator-and-synthesizer driven (RSD) frequency pre-calibration with the aid of the PFTCG enables calibration for extended 100ppm frequency error (2.5x of state-of-the-art systems). This chip is manufactured in 90nm standard CMOS process. The supply voltage to the chip core is globally applied at 0.5V with 12 power- and voltage-domain partitions for sleep-active and voltage-scaling management. The PFTCG is operated at 5MHz with RMS jitter 145ps. The transceiver chipset provides maximum 4.85Mbps data rate with 73.7% power reduction in baseband circuit processing.
