采用工作在2.5、5和10 GHz的改进型Colpitts振荡器和工作在1.25、2.5和5 GHz的交叉耦合LC振荡器实现了超谐波压控注入锁定分频器。所提出的三频带操作通过采用使用pin二极管和负电源的新颖技术来实现。采用低噪声异质结FET和高频SiGe BJT构建的分立式分频器在理论上进行了描述，其功能在实验上得到了验证。此外，短相位噪声分析，这是在文献中缺失，给出。相位噪声，工作频率范围和锁定范围的测量结果。最后，提供了采用0.25µm SiGe工艺实现的5 GHz全差分注入锁定分频器的布局后仿真结果。版权所有© 2010约翰威利父子有限公司.
A superharmonic voltage‐controlled injection‐locked frequency divider, implemented using a modified Colpitts oscillator operating at 2.5, 5 and 10 GHz and a cross‐coupled LC oscillator operating at 1.25, 2.5 and 5 GHz, is demonstrated. The proposed triple‐band operation is achieved by employing a novel technique that uses pin‐diodes and negative power supply. The discrete dividers, built with low noise hetero‐junction FETs and high‐frequency SiGe BJTs, are described theoretically while their functionality is proven experimentally. Additionally, a short phase noise analysis, which is missing in the literature, is given. Phase noise, frequency range of operation, and locking range measurement results are presented. Finally, post‐layout simulation results of a 5 GHz fully differential injection‐locked frequency divider, implemented in a 0.25µm SiGe process are provided. Copyright © 2010 John Wiley & Sons, Ltd.
