Hello everyone:

I'm new here and in circuit field, so I maybe will ask some questions that are not very professional.
Here's an article:
http://ece-www.colorado.edu/~rwe/papers/Powercon5.pdf
and it offers a design plan of an amplifier (detailed circuit is on the last page of this article).
Has anyone tried this amplifier or simulated it in LTSpice before?
I'm trying to simulate it in LTSpice but it doesn't work as I expected, and the simulation result shows very slowly. So I really need some help now, hope I can get it from here.

Thanks.

 

Are you simulating the entire circuit or just part of it? If you post your LTSpice circuit someone may be able to help you.
