陈年老帖又翻出来了,只看了前2页回复,校对3条:
1/ Capacitors and resistors have parasitic inductance, about 0.4nH for surface mount and 4nH for a leaded component.
1. 电阻跟电容都有寄生电感,贴片封装的大概0.4nH,插件的大概4nH。
这个是对的。
2/ If you don't want a high bandwidth transistor to oscillate place lossy components in at least 2 of the 3 leads. Ferrite beads work well.
这个13楼翻译不对,应该是:
如果你不想让一个高带宽的晶体管产生振荡,应该至少在3个脚中的两个脚之间放置损耗元件。磁珠可以工作得很好。
3/ When taking DC measurements in a circuit and they don"t make sense, suspect that something is oscillating.
3.对一个电路采用直流测试并且不起作用时,应该怀疑有元件在振荡
如下翻译更贴切: ...而(测试结果)没有意义,... |
