摘要

提出了一种采用三圈电感的小面积多频段压控振荡器(VCO)，可用于宽带频率合成器。较宽的调谐范围通常需要较大的芯片面积。通过调节三线圈电感的耦合系数和交叉耦合对的寄生电容，可以稳定地实现压控振荡器的三模工作。值得注意的是，三线圈电感器可以在与单个电感器相同的区域内实现。该VCO具有6.6 GHz至13.1 GHz的宽调谐范围，在整个调谐范围内，在1mhz偏移时相位噪声低于-100 dBc/Hz。

A Multi-band CMOS VCO Based on Triple-coil Inductors

This paper presents a small-area and multiband voltage-controlled oscillator (VCO) using triple-coil inductors which can be used for wideband frequency synthesizer. A wide tuning range generally requires a large chip area. By regulating the coupling coefficient of the triple-coil inductors and parasitic capacitance of cross-couple pair, the triple-mode operation of VCO can be stably implemented. Notably, the triple-coil inductor can be realized within the same area as a single inductor. The VCO exhibits a wide tuning range from 6.6 GHz to 13.1 GHz, and a phase noise lower than -100 dBc/Hz at 1 MHz offset over the entire tuning range.
