本文提出了一种宽调谐范围的高输出功率超谐波耦合正交考毕兹压控振荡器。该电路采用低成本SiGe技术制造，ft/fmax为200/250 GHz。正交VCO采用了一种新颖的面积有效的耦合技术，使用二次谐波耦合。实现下变频混频器以提供中频信号，从而实现更容易的测量。在6 GHz调谐范围内，正交输出之间测得的相位不平衡低于±2°。正交VCO可以在55和76.5 GHz之间调谐，具有约100 GHz的记录调谐范围。百分之三十三此外，正交VCO的最大实测输出功率为+10.5 dBm，最小相位噪声为-97 dBc/Hz。整个芯片从3.3V电源汲取303 mA电流，其中正交VCO汲取总电流的140 mA。
This paper presents a wide tuning range superharmonic coupled quadrature Colpitts VCO with high output power. The circuit was fabricated using a low-cost SiGe technology with an ft/fmax of 200/250 GHz. The quadrature VCO employs a novel area efficient coupling technique that uses second harmonic coupling. Downcoversion mixers are implemented to provide an intermediate frequency signal, enabling easier measurement. A phase imbalance below ±2° is measured between the quadrature outputs, over a 6 GHz tuning range. The quadrature VCO can be tuned between 55 and 76.5 GHz having a record tuning range of approx. 33%. Moreover, the quadrature VCO has a maximum measured output power of +10.5 dBm, and a minimum phase noise of -97 dBc/Hz. The overall chip draws 303mA from a 3.3V supply, where the quadrature VCO draws 140mA of the total current.
