摘要

本文提出了一种正交注入锁定振荡器作为三倍频器，通过相位校准方案产生调谐范围为20%、正交误差低的30GHz信号。为了提高锁定范围，采用了基于双注入的拓扑结构，提高了注入效率。采用65nm CMOS工艺实现的正交注入锁频三倍器(QILFT)工作频率为27.3-33.3GHz，正交误差为0.75°和0.2dB，功耗为21.6mW，电源电压为1.2V。

Quadrature Injection Locked Frequency Tripler with Wide Tuning Range and Low Quadrature Error for MM-Wave Applications

This paper presents a quadrature injection locked oscillator as a frequency tripler to generate a 30GHz signal with 20% tuning range and low quadrature error by a phase calibration scheme. To enhance the locking range, a topology based upon dual injection to improve the injection efficiency is employed. The Quadrature Injection Locked Frequency Tripler (QILFT) implemented in 65nm CMOS process works at 27.3–33.3GHz with quadrature errors of 0.75° and 0.2dB, and consumes 21.6mW from a 1.2V supply.
