A 0.24nJ/b wireless body-area-network transceiver with scalable double-FSK modulation

In this paper, the authors reported a BCT that not only consumes the lowest energy with very high sensitivity but also is fully WBAN compatible. It is possible because: (1) the signal propagation principle is more thoroughly investigated, (2) resonance matching (RM) and context-aware sensing (CAS) are adopted, and (3) low-power double-FSK modulation is exploited for the full satisfaction of WBAN requirements.
