This paper proposes an injection locked frequency tripler which can cover 27 GHz frequency band of the fifth generation communication. By adopting the Darlington cell as injectors, the injection current is improved greatly and thus obtains a wide locking range. In addition, an inductive peaking technique is proposed to enhance the fundamental rejection and further improve the locking range. Implemented in 0.13 μm Complementary Metal Oxide Semiconductor (CMOS) technology, the post‐layout simulation in collaboration with electromagnetic simulation is used to validate the proposed injection locked frequency tripler. The Precess Voltage Temperature (PVT) and Monte Carlo analysis are also performed to check the robustness of the circuit. At 0 dBm injection power, the injection locked frequency triple displays a 33.5% locking range and larger than 27 dB fundamental rejection, while consumes 8.3 mW from 1.2 V supply voltage. The core area is 0.56 × 0.23 mm².

具有达林顿注入功能的21.6–30.3 GHz注入锁定频率三倍频器，用于5G通信系统

本文提出了一种注入锁定频率三倍频器，它可以覆盖第五代通信的27 GHz频带。通过采用达林顿单元作为喷射器，极大地提高了喷射电流，从而获得了较宽的锁定范围。此外，提出了一种电感峰化技术，以增强基本抑制能力并进一步提高锁定范围。在0.13μm互补金属氧化物半导体（CMOS）技术中实施后布局仿真与电磁仿真协作，用于验证所提出的注入锁定频率三倍频器。还进行了进动电压温度（PVT）和蒙特卡洛分析，以检查电路的鲁棒性。在0 dBm注入功率下，注入锁定频率三倍显示33。锁定范围为5％，基本抑制大于27 dB，而1.2 V电源电压消耗8.3 mW。核心区域为0.56×0.23 mm²。
