LT Spice problem

Started by krw...@att.bizzzzzzzzzzzz June 1, 2011
I'm trying to add the models of a couple of N-FETs I use to LTSpice.  I'm
getting a simulation-time error that I can't resolve.  Any ideas?  Thanks.

The error: 

|M1: Only a level 9 B3SOI can have 6 nodes

It thinks I have six terminals on my transistor and only SOI models have that
many? Looks like only three to me.

I don't have your symbol so can't run the subcircuit. But when I use just your NMOS model it runs. You have to give V1 a voltage and the LED still needs a model as well.

Model...you mean the one with the long skirt and fancy hat?

Hello krw, I don't have your Mosfet-symbol, but I have been able to get it working. 1. The subcircuit definition was wrong. Below is the corrected line. * D=10 G=20 S=30 .SUBCKT DMG1012T 10 20 30 2. Most of th models for power-Mosfets are subcircuits. Therefore you can use the normal symbol "nmos" or "pmos" with a very small modification. Place a symbol "nmos" on the schematic. Ctrl-right-mouse-click on the placed symbol. A dialog will pop-up. Change Prefix:MN to Prefix:X OK. The attached example has bias point data flags on the nets to better show the operating point. Best regards, Helmut

It seemed to do something here at home. I didn't have time to look at it today. Maybe tomorrow they'll leave me alone so I can get back after it.

Just use the model alone. Package parasitics don't matter unless the LED has to also send out GHz pulses ;-) You can enter a ramp for the voltage source, then you can always see where it loses steam. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

Thanks, Helmut. I still have something messed up. It can't find the model. I should have time to work on it tomorrow.
