I know that I can create my own library files and use .include to specify them. But is it possible to extend the dialog box list for the NPN transistors, for example, so that I can simply select from

John, Yeah. I just put up a version, 2.00l. It lets you duplicate the leakage of PSpice current sources in LTspice. Go to Tools=>Control Panel=>SPICE and check "Add GMIN across current sources" Then

The golden rule in analogue design is that n simulators give n different answers, you have to be able to hand-verify results to some extent. I tell the engineers here, half-jokingly that simulation

John, As has been pointed out, the non-E version of the models do leak much more than the product. That's the model. The E versions are supposed model input bias current and it still leaked too much

Are there any special considerations with using P-spice op-amp macro models with LTspice? I'm trying to simulate a circuit that uses a Burr Brown/TI electrometer op-amp (OPA128 or OPA129) and I'm

Jon, No really, but the cursors are helpful. You can get a quick idea by dragging a box as if you were going to zoom that just touches the peak and valley points and looking at the dy value on the

You may have to download the complete package and re-install from scratch under Wine. I had this problem (sync release didn't work) when I had LTSpice on my machine at work behind a corporate

In my PC running Linux (SuSe 8.1) I installed wine, then I installed SwitcherCADIII. The program seems to work well, I have only a little problem, I am not able to update the program using internet.If

Hehe. Sure! I want folks at Linear to realize it's all appreciated. Works for me. Looks good. Thanks! ... Is there way to get the peak-to-peak over a specific time range? One simple calculation I'd

Jon, Thanks for that wonderful letter you wrote. I forwarded it to the Chief Technical Officer at Linear. Hope that's okay. For your question, it might help you to know that you can see what your {}

I want to start out by saying that I'm a hobbyist, not an electronics professional. When I first heard of SwitcherCAD III/LT Spice perhaps a year ago, I went to the Linear web site with the intent to
