Abstract
In this paper a recently proposed detailed distortion analysis technique is extended to apply in a rather complex VBIC model that contains multidimensional current and charge models. The technique is implemented on top of normal harmonic balance simulation, and it is based on fitting polynomial models for all nonlinear I-V and Q-V sources of the device, and using these to calculate the various contributions of IM3 distortion. The technique is used to analyze a 2 GHz InGa pHBT power amplifier that shows strong bandwidth dependent signal-induced bias shift
本文将最近提出的详细畸变分析技术推广到一个包含多维电流和电荷模型的相当复杂的VBIC模型中。该技术是在法向谐波平衡仿真的基础上实现的，它基于拟合器件所有非线性I-V和Q-V源的多项式模型，并利用这些模型计算IM3失真的各种贡献。该技术用于分析一个2 GHz InGa pHBT功率放大器，该放大器表现出强烈的带宽依赖性信号诱发偏置偏移
