I have a Mac, that already puts me at a disadvantage Smile

I do have an LTSpiceIV implementation that wraps the windows code with the WINE simulator and it appears to work.

I have found CA3080 and LM13700 models and put them in the appropriate places (I think).

But I have not found a readily available OTA symbol, and I'm not sure I'm up for diving straight into designing a new symbol (yes, I can start from an Op Amp, but...).

Anyone have a generic OTA symbol or specific ones for either of these models?

I changed the extension to .txt so I could attach it. Just change it back to .asy.

Hi, there is a Yahoo-Group about Spice, in their Files-Section you can find three ZIP-Files lib_part1 to lib_part3, where are OTAs inside. Maybe it's what you are looking for.

regards

Thanks for the pointer...

Edit: frustrated with Yahoo Groups, cannot seem to find a search, the files are not obvious Sad

Edit2: aha, found the "LTSpiceFiles" group, "LTSpice" group does not have them.

Thank you again, I'm good now Very Happy
