提出一款0.75V供电、功耗仅325µW的跳频合成器，适用于超低功耗无线传感器网络。解决了传统跳频方案功耗过高（需数毫安电流）的问题，实现了40dB无杂散动态范围。
Frequency-Hopping Spread Spectrum (FHSS) for ultra-low-power Wireless Sensor Networks (WSNs) is the power dissipation of existing solutions. Whereas FHSS would make WSNs very robust and secure in difficult fading (indoor) environments, state-of-the-art solutions based on PLLs and digital frequency synthesizers require supply currents of several milliamperes [1,2]. A solution that consumes significantly less than 1mA is required to enable FHSS in autonomous WSN nodes. Power dissipation should also be independent of the hopping speed, as fast frequency hopping allows for fast synchronization, and results in minimum power overhead in the WSN. Furthermore, a fast hopping speed without power penalty allows designers to reduce the transmitted SNR by trading off hopping speed for
