本文提出一种基于次谐波注入锁定的超宽带（UWB）快速跳频频率生成方法，解决了WiMedia UWB系统中本地振荡器（LO）生成的多频率、低杂散、快速建立时间等关键挑战。采用90nm CMOS工艺实现，验证了该方法的有效性。
high-data-rate WiMedia UWB systems is to design an efficient LO generation. On one hand, it must fulfill the stringent requirements (multiple LO frequencies, spurious, settling time and I/Q imbalance), and on the other hand it should yield minimized power consumption, area and complexity. Various different UWB LO concepts have already been proposed [1-4], but none of them seems to give a clear advantage over the other. In this work, a completely different approach for LO generation is presented that uses sub-harmonic injection locking. Measurement results in 90nm CMOS clearly show the chip meets the required performance, while it has the lowest area and power as compared to the reported state-of-the-art. The WiMedia Alliance proposed to channelize the UWB available
