以前谈到电源去耦,我警告过糟糕的去耦会增加放大器的失真。一位读者问了一个有趣的问题,去耦电容的接地脚应该在哪里接地才能消除这个问题呢?
In a previous blog on supply bypassing, I cautioned that poor bypassing could increase distortion of an amplifier. A reader, Walter, asked an interesting question… where should you connect the ground of a bypass capacitor to avoid problems?
这个问题升级到关于正确接地的技术。题目太大了,不过我也许能够提供一些启发性的例子。This raises questions regarding proper grounding techniques. Wow. Big topic, but I may be able provide some insight with a couple of simple examples.
