我的记忆方法也差不多:考虑加载效应断开环路时,应该分别把非理想反馈网络的输入输出阻抗体现出来。对于连接前馈放大器输入端的反馈网络电路,我们需要将反馈网络的输出阻抗体现出来,那就是把反馈网络的输入信号源置零,也就是说,对于前馈放大器的输出信号是电压(电流)时,要把反馈网络的输入端口置零,即短路(开路)。
All about Circuits,我希望开始一个系列来讲述analog IC中比较抽象的部分,实现数学和物理概念之间更紧密的联系,从而进一步深入对电路的理解。 这一章中,我将主要围绕反馈系统的稳定性问题,力图分析开环前馈函数的波特图,Loop Gain的波特图,闭环系统的波特图以及根轨迹图之间的联系。很多内容出自于我学习过程中困扰良久...
来源:EETOP编译自allaboutcircuits 本文您将了解到史密斯圆图的历史和来龙去脉,以及它与反射系数的关系及如何使计算阻抗更容易。 史密斯圆图是一种图形化的 RF 设计工具,它使我们能够轻松计算将给定阻抗转换为另一个阻抗所需的阻抗匹配网络的组件。 早在1930 年代,史密斯圆图就是高频工作的主要内容。对于今天的计算...
Invensas总裁Craig Mitchell称DBI Ultra是“最终的3D互连和集成解决方案。这种具有生产价值的die-to-wafer混合键合平台使半导体行业能够超越摩尔定律,为下一代电子产品提供前所未有的2.5D和3D集成灵活性。” 值得一提的是,摩尔定律在技术上是指芯片上晶体管的密度。也许最准确的说法是,Xperi在这里避免了挑战摩尔定律所...
