Hi, thank you for your reply. When you get the chance, I would appreciate if you could re-upload it. Thanks a lot Marco

Thank you sir for your valuable help.

I am trying to create a model for the MMBTH81 transistor. I extracted the following model from the datasheet and put it in a LTspice schematic with a directive. .MODEL MMBTH81 PNP(Is=10f Xti=3 +

I am new to LTSpice but I have experience with AutoCadd. Pins 8 and 16 are missing and I can't add them to the .sym model. How do I power this IC? Any advice or workaround will be appreciated. Steve

Hello, I also had a problem to update LTspice on two WIN7 PCs the last week. When I clicked on Sync Release, it simply did nothing. It behaved like when another LTspice is open. I rebooted the PCs and

I can't install the latest update in linux. It certainly doesn't go in painlessly like the last one did, and may need shoehorning in. That's a pity, because I uninstalled the older version. Is this a

Hi Andrew. Look http://ltwiki.org/index.php5?title=Components_Library_and_Circuits File is LTspiceIV.zip. It contains a files Valvol.lib and UC3825.asy. Bordodynov.

Hi. My file 100MEG LTspiceDoc contained different files with instructions on using LTspice. These files I found on the internet. Files including in Russian. Links to some of them are in this group.

Hello Andy, Thank for sharing your thoughts with me. I discover something that I do not understand. Maybe you or other people can answer my questions. All 2stages_2CascodeDiff_ACsim_test1_orig.asc,

Hello Ron, If you want 100Hz resolution, you have to simulate at least 1/100s=10ms. I have uploaded an example "fft10meg.asc" to the Temp-folder folder. I simulated 20ms.
