关于这个问题, 我专门的在TI社区发表了提问。
今天收到Ti的回复 如下:
It's not dominant pole, it does not cause a pole. It is very strange, might well lead to instability; in fact I believe it definitely causes instability, unless there is some weird load at the output we don't see that advances phase.
That is why I said before, if this is a diy schematic, all bets are off, meaning: it may work or it may totally f*uck it up. I don't recommend that DIY enthusiasts make such an attempt.
Then it oscillates and they praise the 'clean and detailed reproduction'. Go figure...
在我看来 说什么极点补偿的就是一大笑话,还信誓旦旦,明明就是在误人子弟。 还是那句话 ,科学面前来不得虚假 |
