摘要

本文设计了一种采用混合控制方案的超宽调谐范围12 ~ 23 GHz的压控环形振荡器。压控振荡器(VCO)采用前馈插补拓扑方案和变容二极管负载电容变化方案来控制振荡。测量结果表明，在超宽调谐范围内，压控振荡器的频率-电压特性具有良好的线性关系。

12-23 GHz ultra wide tuning range voltage-controlled ring oscillator with hybrid control schemes

This paper presents the design of a voltage-controlled ring oscillator that has ultra wide tuning range of 12 to 23 GHz with hybrid control schemes. The voltage-controlled oscillator (VCO) uses a feedforward interpolation topology scheme and a varactor diode load capacitance variation scheme to control the oscillation. The measurement result of the VCO shows good linearity in frequency-voltage characteristics over the ultra wide tuning range.
