Its not a case of comments not being allowed, its just that the OP's topic is often derailed by discussions about some aspect of another members post/s, which does not help the OP to solve his problem.
The OP was asking for an ac analysis of a non-linear and time-dependent circuit.
In my post#8 I have pointed to the fact that an ac analysis requires a linearized system. That was my answer to the OP's question.
If you feel strongly enough about the accuracy of information with any post, I would suggest you create a new thread, so that we can all discuss it without disrupting the OP's thread.
So you recommend a new thread just for answering questions which may arise in another thread?
In many cases what an OP is trying to achieve is not explained to us and we have to start from somewhere in the hope we can suggest a solution or an alternative method.
As you can see from the attached image [post#5] the OP wanted to know why his circuit for AC analysis did not work, the reason why was posted to him.
Yes, and I gave an answer in post#8.
I suggested a method I had used, either a fast comp or a fast OPA to square up the AC analysis sine wave, this method has limitations
I would now expect the OP to consider variations on this method and its drawbacks and get back to us with his comments.
Yes, and I had a question to the method suggested by you. Why didn't you answer? It was a pure technical question - perhaps interesting for the OP and other readers of this thread.
