摘要

本文提出了一种基于单次全摆幅、全带宽非线性矢量网络分析仪(NVNA)测量在特定双音激励下进行场效应管准静态(QS)自动建模的方法。该程序利用新定义的非线性函数采样(NFS)算子和二维时域波形分析，允许通过求解线性方程系统来识别模型。该模型已在2.5 GHz和5 GHz连续波(CW)工作以及2.5 GHz三阶互调失真(IM3)预测下进行了验证。

Nonlinear FET Modeling from a Single NVNA Measurement by Nonlinear Function Sampling

We propose an automatic method for FET quasi-static (QS) modeling based on just one full-swing, full-bandwidth (BW) Nonlinear Vector Network Analyzer (NVNA) measurement under a specific two-tone excitation. The procedure leverages on a newly defined Nonlinear Function Sampling (NFS) operator and on 2D time-domain waveform analysis, allowing for model identification by just solving a system of linear equations. The model has been validated under continuous-wave (CW) operation at 2.5 and 5 GHz, and for 3rd-order intermodulation distortion (IM3) prediction at 2.5 GHz.
