I'm liking it so far. Remember that a MOSFET's gate-source is usually limited to +/-20v.

There are several substraction existing, I try to figure out how to manage them. This was a first (and very wrong) approach. I try to make adjustments. I'll describe you exactly the main problems and maybe we can find solutions.

It's quite OK. I mentioned that for the benefit of the other readers of the thread, mainly. Keep up the good effort!

Reducing the level shifter pull-up resistor is one way to do so. i have attached it if you are interested.
by what open up?

The file is opened up with the excellent and free electronics simulator, LTspice IV. I love so much about this design tool that Linear Technology produces.
