A V-band low-dc-power wide-locking-range divideby-6 injection-locked frequency divider (ILFD) using a 90-nm CMOS process is proposed in this letter. The proposed innovative topology is composed of current-reused oscillation cores with transformer coupling. Moreover, the dc bias of the injectors can be properly applied to widen the locking range (LR). With a core dc power of 5.6 mW and an input power of -5 dBm, the measured maximum locking is 5.6 GHz (9.8%) from 54.5 to 60.1 GHz. When compared to the previously reported V-band ILFDs, this work features a high division ratio, low dc power, wide LR, and good sensitivity.

使用变压器耦合的 V 波段 CMOS 低直流功率宽锁定范围 6 分频注入锁定分频器


本文提出了一种采用 90 nm CMOS 工艺的 V 波段低直流功率宽锁定范围除以 6 注入锁定分频器 (ILFD)。所提出的创新拓扑由具有变压器耦合的电流复用振荡核心组成。此外，可以适当地施加喷油器的直流偏压以扩大锁定范围（LR）。核心直流功率为 5.6 mW，输入功率为 -5 dBm，测得的最大锁定频率为 5.6 GHz (9.8%)（从 54.5 GHz 到 60.1 GHz）。与之前报道的 V 波段 ILFD 相比，该工作具有高分频比、低直流功率、宽 LR 和良好的灵敏度。
