摘要

本文讨论了LC耦合谐振器滤波器的一个实例。采用灵敏度分析方法估计了由LC谐振器组成的电路中Q因子的有限值所引起的幅值响应失真。结果，给出了振幅响应失真的广义公式。提出了预失真技术的改进版本。利用Q因子有限值的单元，利用预失真构造符合给定频率响应形状的滤波器。

Tuning of coupled resonator LC filter aided by SPICE sensitivity analysis

In the article an example of LC coupled resonator filter is considered. Sensitivity analysis is used to estimate distortion of amplitude response caused by finite value of Q factor of LC resonators the circuit consists of. As a result a generalized version of formulas for distortion of amplitude response, is formulated. Next improved version of predistortion technique is presented. Predistortion is used to construct filters adhering given shape of frequency response using elements with finite value of Q factor.
