摘要

本文提出了一种包含偶数阶项的改进行为模型,用于模拟非线性放大器多音激励中观察到的不对称IMD分量。对于一个采样放大器,只构造了奇阶模型(OOM)和偶阶引入模型(EOM),并进行了比较。结果表明,引入偶阶项除了降低模型多项式阶数外,还能提高模型的有效范围和精度。

A nonlinear model for amplifiers with memory
In this study an improved behavioral modeling including even order terms is proposed to model asymmetric IMD components observed in the multi-tone excitation of nonlinear amplifiers. Only odd order model (OOM) and even order introduced model (EOM), proposed model, are constructed and compared for a sample amplifier. It is showed that introducing even order term is improved the model validity range and accuracy in addition to the decrease model polinomial order.
