本文提出了一种支持IEEE 802.15.6 WBAN标准的多通道、多调制发射机，采用相位插值双注入DLL基合成器实现FSK/GMSK/QPSK/π/4-DQPSK调制，能量效率达110pJ/b，解决了可重构无线发射机的高能效和多标准兼容问题。
of Singapore, Singapore, Singapore 1 2 The IEEE 802.15.6 Wireless Body-Area-Network (WBAN) standard has recently specified narrowband (NB) PHY covering GMSK and D-PSK modulations targeted at varying data rates [1]. There are also reported energy efficient FSK or QPSK transmitters for biomedical applications [2,3]. Hence, a reconfigurable TX that can support multichannel and multimodulation with reconfigurable data rate, spectrum and energy efficiency would be desirable. Although a conventional mixer-based or fractional-N-PLL-based TX with two-point modulation [4] can achieve the aim, the need of power hungry blocks and sophisticated calibration does not lead to power-efficient solutions. On the other hand, energy efficient injection-locked FSK or QPSK TX with good noise performance does not provide
