摘要

为了提高单片压控振荡器(VCO)的仿真精度，本文提出了一种lc -tank的表征和建模方法。结合G-S-G(地-信号-地)测试结构的稳健设计和精确的片上表征，该方法易于实现，特别适用于采用先进CMOS和BiCMOS技术制造的高频压控振荡器的建模。该方法允许提取包括所有RLC-tank寄生在内的LC-tank电容器，因此具有重要的建模精度提高。该方法已在几个lc -tank(振荡在6和10GHz之间)的情况下进行了验证。罐式电感器和电容器在晶圆上的性能高达50GHz。

Bicmos LC-tank characterization and extraction of small signal equivalent circuit

In this paper, a procedure for characterization and modeling of LC-tanks is proposed to enhance simulation accuracy in design of monolithic Voltage Controlled Oscillators (VCO). This efficient procedure is easy to implement combining robust design of G-S-G (Ground-Signal-Ground) test structures and accurate on-wafer characterizations, and it is in particular suitable for modeling of high frequency VCOs fabricated in advanced CMOS and BiCMOS technologies. The methodology allows the extraction of LC-tank capacitors including all RLC-tank parasitics and therefore features an important increase of modeling accuracy. The method has been validated in the case of several LC-tanks (oscillating between 6 and 10GHz). The tank inductors and capacitors have been characterized on-wafer up to 50GHz.
