Hi! I need to add a DMMT5401 matched transistor pair to a simulation. Does anyone know if a symbol for a matched transistor exists? I have not found one so any help would be appreciated. I have the

This question comes up on a regularly repeating basis every few weeks or months, so lets review once again and hopefully this message can be referenced in the future as a response. ? Basically there

I'd like to know if anyone has created an A, B or C size schematic sheet symbol that they would share with me? These are the standard engineering schematic sheets with zone letters and numbers.

Hello Peter, It looks like Mike has now fixed this problem. I just updated my LTspice. Tools -> Sync Release The file Changelog.txt contains an entry about a netlist fix. 12/12/13 Fixed an error in

Hello Peter, Have you reported this problem? I tried with a simple example, but it has been OK. I don't see any error. Could you please upload a test case? Best regards, Helmut

I updated LTspice yesterday. There is replacement of the jumper with 0 value of the resistor, but the Export Netlist is not working now properly. The values of the resistors are replaced with

Dear Mr Andy, Thanks for your suggestion. I chose one potentiometer from the all_files folder. But still I am unable to simulate my circuit if I use this component in my circuit. Same error message

Thanks you for help and it is working but can you please explain me how did you do it because i spent many hours of searching and trying, i have even follow all the tutorial but it has never worked.

Some one or two months ago mention was made of a book “The LTSPICE IV Simulator” written by Gilles Brocard, published by Wurth Electronik, ISBN 978-3-89929-258-9. I have used LTSPICE for about

In any event the resultant "spectral accuracy", even if optimized for some set of conditions, resolution, and bandwidth of spectrum, will be directly dependent on the accuracy of represented

There is a solution to LDO-s that work well enough using a level 2 switch that was described here on the forum. I did my solution for a L4940 family regulator that works well enough. You won't be able

Thanks again, Frank. I should mention your file is named "opamp stability 2.asc" for those who may be looking for it. To me, it is one of the most sign

Hi Rick, Thanks for the explanation. My version only works with left click. You really should take a look at Frank's solution. I extended the frequency range to .ac dec 1000 1m 10Meg Two runs gave the

Hi Steve and Andy Youll only be able to see the side bands if the sample is long enough to encompass an integral number of modulation periods. (and an integral number of carrier periods. The two
