Help with PSPICE...

[step-dawg]

Hi,

Is anyone here familiar with Pspice? I want to put the value of infinity for a parameter of a resistor. I'm using a parametric sweep and I want to use infinity in the value list. is there a way to do this? Thanks for any help.

sorry, i don't get the spice channel

Well, that was helpful, thanks.

Anyways, seriously, anyone familiar with PSPICE?

I don't believe there is a way to do this. This is one of the known issues with modeling MOSFET transistors in the default pspice package, since theoretical MOSFETs have infinite input resistance, but you have to stick in a value anyways. I think what you end up doing is sticking in a very high value for R, there shouldn't be that much of a difference.

I checked my reference and there doesn't appear to be a way to do this. If possible, I'd go with OuterSquare's suggestion and just put the highest value allowed in.

Cool, I knew I could count on my fellow ATer's for help. Thanks guys.
