This paper provides an all-digital smart temperature sensor with dual-mode transceiver chipset for Wireless Body Area Network (WBAN). The measurement results show that the proposed temperature sensor achieves a maximum temperature error<0.6?C within the range from 20?C to 50?C. And a Phase-Frequency Tunable Clock Generator (PFTCG) is designed with frequency and phase tuning capability on the fly. This chip is manufactured on a standard 90 nm CMOS process. The supply voltage to the chip core is globally applied at 0.5 V with 12 power-domain partitions for sleep-active and voltage-scaling management.
