本文对InP HBT小信号模型进行了灵敏度分析和不确定性估计。灵敏度的解析表达式是在直接提取固有参数的基础上，根据测量的S -参数导出的。此外，还讨论了固有参数随频率变化的不确定性，以获得更可靠的提取结果。利用灵敏度分析得到了各参数的最优解。在45 MHz ~ 40GHz的频率范围内，5 × 5μ m2inp HBT的S -参数与模型的S -参数吻合良好。
In this paper, a sensitivity analysis and uncertainty estimation of small‐signal model for InP HBT is presented. Analytical expressions for sensitivity are derived in terms of the measured S‐parameters based on the direct intrinsic parameters extraction. Furthermore, the uncertainties of the intrinsic parameters vs frequency are discussed to give more reliable extraction results. The optimal solutions of the parameters are obtained by utilizing sensitivity analysis. In the frequency range of 45 MHz‐40GHz, good fits between the measured and modeled S‐parameters are achieved for 5 × 5μm2InP HBT.
