本文介绍了一种用于毫米波本振产生的宽带注入锁定三倍频器。传统的C类注入与D类尾开关相结合，实现了锁定范围的显着扩展。所提出的技术的有效性的理论见解。一个28纳米CMOS原型实现了57-74 GHz的工作频率与11 mW的功耗，无需调谐或校准。
This letter presents a wideband injection-locked frequency tripler for mm-wave local oscillator generation. Conventional class-C injection is combined with class-D tail-switching, achieving significant extension of the locking range. Theoretical insights on the effectiveness of the proposed technique are provided. A 28-nm CMOS prototype achieves 57–74 GHz operation with 11-mW power consumption, without the need of tuning or calibration.
