中文摘要:

本文以OPA691芯片搭建的放大电路为样本,研究了在宽带放大中受驱动电缆长度影响的自激振荡现象,分析了成因并构建了解释模型,最后提出了消除此种自激振荡的简易有效方法。本文对宽带放大电路设计的消除自激振荡提供了一定参考。

英文摘要:

Based on a sample of broadband amplifier of TI OPA691,this paper studies the self-excited oscillation phenomenon which caused by the driving cable length. This paper analyzes the affection of the self-excited oscillation and builds a model to explain this phenomenon. Finally, this paper comes up with an effective design method to eliminate the self-excited oscillation. So it provides a reference for eliminating the self-excited oscillation in the broadband amplifier circuits.
