Go back to sleep. You're smarter then.

That is the best you have? Pitiful. The pet rock i never got would be embarrassed to meet you.

please answer carefully.

If it's your pet rock, it's understandable.

I was wrong. You aren't smarter when you sleep. You're always comatose.

button. That

comatose.

Hoist on your own petard.

I have added the SPICE netlist below. I am using a standard op-amp LMH6629. The modelcard files are added after the main file. I am using ngspice-23 on a Fedora 14 machine running GCC 4.5.1 Please note that the circuit is still experimental, and so not optimized or efficient.

Hello Daku,

Your Mosfets are too weak. They only have Idmax=2mA. The ratio W/L for Power-Mosfet is more like 10000 to 100000. This means W should be many m (milli) instead of u.

Example: M1 4 7 0 0 M_NMOS L=1.2u W=50m

Best regards, Helmut

Lots of people (including me) run run ltspice on linux using wine. it's easy to install and runs well (somewhat dependant on window manager settings). The provider (linear technology) is biased towards their own parts. One advantage is the ASCII netlists produced by this GUI application are easily posted on usenet. And thus easily run and understood.

In addition to wine you need to also install "xchm" if you want to use the online help.
