Fabulous guys. I had thought it might require me to write my own test setup but it's good to hear that these have been made available. I'm not talking about anything exotic here. I only mean BJTs,

What you say about this is true, hFE does have significant statistical spreads, but the datasheet limits are probably set at 3 sigma (any outside this being rejected, being only a 0.3% loss). 3 sigma

You put your device and its model into a curve-tracer .ASC and set it up to produce (if it will) the same curves as in the data sheet. Compare the results. You can find curve-tracer .ASCs by going to

I have searched for this and can't find anything that is generic and at my level but, is there somewhere information on a sensible validation procedure for the simple classes of model?? I mean

Christoph wrote, "Maybe there were meant to be time/value tuples in angle brackets and they were fallen victim to the HTML conversion?" I think they just got edited out or omitted by accident. Andy

That’s what I was initially thinking of (and also posted it). What you are mentioning is BNF (Backus-Naur form of descripion of higler level programming language syntax). Only I was missing the left

Alexander Bordodynov's greatly expanded standard.xxx libraries have been available for years. Alex is a highly valued member of the group. I don't know the provenance of the models in his collection,

Some valid points, but I think the proposal is not 'either/or'. I see no objection to putting the expanded files in a new subfolder of Files, as long as it has a warning about how to use it and not

I'm not against a repository of models - we already have one in the group 's Files section. But I am against trying usurp the standard libraries. Most people coming to this group, at least initially,

It sounds a very good idea, but keeping the same filenames could cause untold confusion. Is there any way of making the names different?? The only thing I can think of is making them all upper-case,

Hello All, Members could maintain a set of the standard.xxx files for use by the group. I've been doing that for many years now. If the group retained a set of maintained files in an easy to reach

There is also? JSPICE "JSPICE is a simulator for superconductor and semiconductor circuits, and is based on the general-purpose circuit simulation program SPICE2; it is incorporated with the

I wonder if it might be worth the while of those of us concerned about Analog Device's inaction in these matters to take to social media to suggest alternatives to LTSpice. With apologies to Arlo

I have uploaded an LTspice VDMOS model for the Onsemi BSS138 </g/LTspice/files/z_groups.io/Lib/BSS138.zip>. The uploaded zip includes a model validation report that compares the key

Dave, Of course he was, although I find it more instructive to show someone how it does work, rather than explaining how or why some other example does not work. All for now

eewiz, I think Bonkers was mixing absolute timing with relative timing notation. If you delete all of the + signs at the beginning of the lines, it makes pretty good sense, as absolute times. It took

Hello Christoph, Bonkers may be leading you down the primrose path. If you follow Bonkers' advice the length of bit[1] will be twice the length of bit[0] and the length of bit[2] will be three times

Kerim, can you simplify your 2-winding transformer model a little?? Having an ideal transformer at its core, I think you can "push" the other elements through it to the other side and combine them.?

OT: Obviously, implementing the push-pull topology is much easier than the bridge one. But this has a price: [1] The amplitude of the driving PWM voltage is doubled. It is from Vbat to –Vbat instead
