This article presents and analyzes a wide-locking range divide-by-5 injection-locked frequency divider (ILFD) manufactured in the TSMC 0.18- $\mu \text{m}$ processes. The ILFD uses the balanced injection method and uses the pure harmonic mixing approach at low injection power, and it is designed with an RLC dual-resonance resonator. The harmonic mixer relies on the self-generated second harmonic, which increases with injection power. Because of no narrowband filter as used in the linear mixer counterpart, the divide-by-5 ILFD uses a wideband design method. In addition, the ILFD enhances the divide-by-5 locking range via the overlapped dual-band locking ranges as verified by both experiment and simulation. At the drain–source bias ${V} _{\text{DD}}$ of 0.8 V and at the incident power of 0 dBm, the locking range of the divide-by-5 ILFD is 3.6 GHz, from the incident frequency 13.0–16.6 GHz with the percentage 24.3%. The core power consumption is 4.09 mW, and the die area is $1.02\times0.93$ mm².

基于谐波混频的宽锁定范围 RLC-Tank 平衡注入分频 5 注入锁定分频器

本文介绍并分析了采用 TSMC 0.18- 制造的宽锁定范围除以 5 注入锁定分频器 (ILFD) $\mu \text{m}$ 过程。ILFD采用平衡注入方式，在低注入功率下采用纯谐波混频方式，设计再生资源控制中心双谐振腔。谐波混频器依赖于自生二次谐波，随着注入功率的增加而增加。由于线性混频器中没有使用窄带滤波器，因此 5 分频 ILFD 使用宽带设计方法。此外，ILFD 通过重叠的双频带锁定范围增强了除以 5 的锁定范围，正如实验和模拟所验证的那样。在漏源偏置 ${V} _{\text{DD}}$ 0.8 V 和入射功率为 0 dBm 时，5 分频 ILFD 的锁定范围为 3.6 GHz，入射频率为 13.0-16.6 GHz，百分比为 24.3%。核心功耗为 4.09 mW，裸片面积为 $1.02\times0.93$ 毫米²。
